stop faffing about and bolt them on ffs
You're right of course.... but where's the fun in that?Saturday the deed will be done... until then I'm still awaiting discs, spacers, Brembos back from Godspeed, the pads did turn up yesterday though

I think that kits a bloody bargain and yes I have those brackets from this guy for mine
^^^^This^^^^I would have saved myself about £50 if I'd just bought that complete kit with the calipers included
Part: Cosworth 2 Wheel Drive Brembo 4pot 325mm Brake Caliper & Bracket kit
From: EBay - Caprisport Direct (oldphonebloke)
eBay item number: 221290558563
Cost: £325.00
Part: Genuine Brembo Brake Pads (Brembo part no: P 06 018)
From: http://www.carparts4less.co.uk
Part Number: 10111017A
Cost: £35.31
Part: Genuine Brembo Discs
From: http://www.apd.co.uk/
Part Number: 09.5486.50
Cost: £120.00
Part: Hubcentric 12mm wheel spacers & Studs (Front & Rear)
From: EBay - Mtec Online
Part Number: CRP130A55
Cost: £73.98
Total before fitting: £554.29
I've ended up shelling out £601.53 so wasted £47.24, but only because the EBayer who sold me the calipers advertised them as fully refurbished but when they arrived I found two pistons were damaged.
If the calipers were as described my complete package would have come to £450
, essentially I took a gamble that could have paid off but ended up costing me a bit more, in hindsight what I should have done was just buy the complete Caliper & Bracket kit from Caprisport Direct (oldphonebloke).But as we all know in life...... hindsight is wonderful thing
Saying all that £47.24 is not the worlds biggest loss, and £601.53 is still astonishingly good value for money for what I hope will prove to be an excellent brake upgrade.
Do keep in mind that this upgrade only works with 16" front wheels or larger, so if you need to buy a set of 16" rear wheels to replace your standard 15" fronts just to make these brakes fit it starts getting very pricey indeed.
Fortunately the owner of my car before I bought it had the foresight to add the 16s for me

I think I paid £100 for mine ... got them refurbed by a couple of guys in the New Forest (can't remember offhand how much it was but they look awesome) ... my existing front tyres were *KNACKERED* for the second time after being poorly tracked up *TWICE* so I just used the opportunity to offset part of cost of what I would be spending on the tyres against what it would cost me for new front wheels and boots. 
Phil
That was good deal Phil Phil
Being realistic I'd budget £150 per 16" Imola wheel plus £65 per wheel for a proper refurb, and you need to assume the wheels will need reburbing.
http://www.ebay.co.uk/itm/TVR-CHIMAERA-ALLOY-WHEEL...
A little cheaper here....
http://www.ebay.co.uk/itm/TVR-Chimaera-16-Imola-Al...
So Dungman should budget spending around the £400 mark to put nice freshly refurbished pair of 16" Imolas on the front of his Chimaera, but could equally get lucky like Phil and do it for a lot less.
Estorils are of course much rarer so will be more pricey still.
Either way you are also in for a pair of 16" front tyres so that's another £180 fitted, so while you might do it cheaper I'd say you could easily spend as much on the wheels and tyres as you have on the full brake upgrade.
Anyone starting out with standard 15" front wheels is potentially looking at £1,000 all in for the complete upgrade including calipers, brackets, spacers, extended wheel studs, pads, discs, 16" wheels and tyres.
That's not to say its still not way better value than any other big brake conversion, because any conversion using a disc size over 300mm will need 16" front wheels.
Your other option is to see if the guy from Caprisport Direct (oldphonebloke) offers a bracket kit that pairs the Brembo calipers with a 300mm disc, which I have a feeling I've seen. That way you can stick with your standard 15" wheels, and assuming your not driving all out on a track I doubt you'll notice much if any loss in braking performance over the big Mk1 Focus RS 324mm dinner plates?
Talking of those genuine Brembo Mk1 Focus RS 324mm discs, I've just found them for sale for £16 less than I paid, why does that always happen

Hi Bremboids
Had a closer look at the bracket & bolt kit from Caprisport Direct (oldphonebloke) today and.... hmmmmm that looks odd.... the M12 bolts appear have different thread pitches?
The four alen cap head bolts that come with the kit looked like a regular M12 pitch to me but the four hex heads confused me as the thread is clearly finer?
A thread gauge confirmed my suspicions, the alen cap heads are the common M12 x 1.75 and the` hex headed bolts are a rather oddball M12 x 1.5.
Panic set it as I tried to think where I might find a super rare M12 x 1.5 tap before I leave the house for Phased Towers at 7.30am tomorrow?
Fortunately logic stepped in to discipline me as I realised the Italian brake monkeys at Brembo may have been the ones who chose this strange thread, a quick check confirms oldphonebloke knows his stuff as the "Whop Stoppers" have a M12 x 1.5 thread chased into their mounting holes.
So a typically long ChimpOnGas post just to tell you all a Brembo caliper has two mounting holes with the rather unusual M12 x 1.5 and to warn anyone stupid enough to wind the supplied M12 x 1.75 alen head bolts into their Brembos will likely destroy their lovely new calipers.
Therefore....this thread.. is just a thread.. to highlight thread differences
See what I mean...Init

ep should have mentioned this earlier too thats an odd thread even in M12 terms, I found out while making up my kit and then talking to Alex he piped up a couple of days later stating the same gotcha to which I replied "I know I found out" I forgot to mention purely because I have had mine about 12 months and still not on the car ..... yet
Buggeroids, just realised I should have snagged four M12 x 1.75 Nylock nuts today Fortunately the nice Mr Phased has confirmed he has the common M12 x 1.75 tap on site.
Until tomorrow
Well the B-b-ber Brembos are on, a massive thanks goes to Phased for letting me use his ramp.
The spacers I bought needed re-engineering
and the studs that came with them were the course spline rather than the fine Ford spline used by TVR
The Oldphonebloke bracket kit comes with spacers and a handful of washers, the brackets themselves can be fitted in two ways but as we discovered only one way is correct
As it turns out the spacers offered in the kit weren't needed and given there are no instructions whatsoever these spacers are a bit confusing, stamping "TOP" or an arrow into the brackets wouldn't go a miss either.
What we found was four thin M12 0.5mm shim washers (one for each M12 bolt) was all that we needed. With the brackets the right way up and the 0.5mm shim washers in place the whole thing bolted together with perfect and even caliper spacing to the discs.
Finally I found you could probably cut an M12 thread into the two mounting holes without drilling, but I didn't fancy shearing a super hard tap in the hub especially as it was the only M12 tap we had, so I did bring the holes out fractionally but it was more of a ream than a drilling.
Cast iron is never the best material to tap, there are certainly better metals to cut a nice clean thread into but the end result was acceptable and safe. A smear of thread lock and a check with the torque wrench and my new Brembo calipers are going nowhere!
Brakes bled, wheels and spacers in place, and my 16" Imola front wheels spinning freely I took a quick blat up the Phased test track then back again for a wheel re-torque. All that remained was to bed the pads in on the run home, they certainly got better and better with every test application as I slowed the car rapidly from speed five of six times on a clear M25.
Today I did further 200 miles on my new brakes and they're now revealing their true power, what I like best of all is their progressive OEM feel.
To be fair my old standard calipers needed a compete overhaul, they were sticking on their sliders so hanging on fractionally and generally performing very poorly.
So I've gone from the very tired standard single piston calipers that were half gripping 260mm discs, to a set of completely overhauled four piston Brembos clamping down hard on giant 324mm discs.

Told you they were good.
Fekin awesome mate We all like to focus on making our cars go faster, so it comes as quite a surprise when you realise the truth is making them stop better is really where it's at. A couple of grand buys you some better heads that will give you 50hp t best, a set of Brembos will likely cost you a quarter of that and on the right road may well give you the greater advantage.
My Brembos cost me £600 and I'm starting to think it could be the best £600 I've spent on the car so far. Powerful and progressive, these brakes inspire massive confidence which makes you way faster because you can hold onto your speed for longer and brake much much later. I thought the car would move about more, I thought these mega brakes may unsettle the balance, but the reality is the polar opposite, I feel safer and more relaxed which means without consciously thinking about it my pace naturally goes up.
Today I completed a 200 mile run which including one moment where I had to proper lean on my new stoppers hauling the car down from 106 leptons to 40, boy what brakes
. But feeling very impressed with my new Brembo setup it all came together on my favourite 3 mile stretch of winding country road between Harefield & my house, with my trust in the new anchors now strong I gave them a little back lane work out 
With the dark road ahead lit with my perfected LED lights and now with brakes that inspire massive confidence, 'Ol Gasbag' positively devoured this short but sweet path to pleasure and has finally become what I'd call a proper A-B back road weapon
A big thanks from me to everyone who helped me with the Brembo mod, especially the very patient Phased who really is a super generous chap and a true credit to the TVR community

Glad your pleased Dave.
Just to give a visual of the change, this is my 324mm disc against the standard 500 disc, so your upgrade, is even greater
A lot of people assume the brakes on a 4.0 litre car are smaller than the 5.0 litre cars, this is of course not true at all. Just to give a visual of the change, this is my 324mm disc against the standard 500 disc, so your upgrade, is even greater
Early 4.0 litre Chimaeras did indeed have smaller brakes than early 5.0 litre cars but this didn't last long as by mid/late 1996 all Chimaeras had the same 260mm front and 273mm vented rear disc setup irrespective of engine size, my part facelift late 96 4.0 litre being one of the first to benefit from what you might call early 5.0 litre brakes that went on to become simply Mk2 Chimaera brakes that were used across the board.
In 1996 TVR simply consolidated the braking system across all Chimaera models which I'm sure made complete sense on the production line, the smaller front discs and non-vented rear setup were ditched completely which looking at the tiny dimensions of the things was a very good idea indeed, lets not forget that even a standard 4.0 litre car is easily capable of exceeding 150mph.
On the subject of spacers I didn't like the way the hub centric ones I'd ordered sat in my wheels, not sure how but somehow I ended up with the wrong kit, my recommendation to other's doing this conversion is to measure up carefully and call the spacer supplier to make sure you get the right spacers that fit correctly and tell them you want fine spline studs too.
Putting a "bits-N-bobs" kit of parts together yourself is all well and good but you do need to make sure everything is spot on and fully understood before you blunder in and press "buy it now" on FleaBay.
The minor lessons learned and put aside for a minute this Brembo brake conversion is absolutely fantastic, and if you don't want to fit used brakes to your car I discovered Brembo still make these fantastic four piston calipers. They come from the Brembo Gran Tourismo range and can be purchased for an eye watering £1,500 a set, this is because they are an OEM quality product so in truth are worth every penny of the £1,500.
Your other option is to buy them used from Ferrari breakers because they were fitted to the 200 MPH 1,800kg 550 Maranello, 360 & 430 moodels as well as all Masserati models of the same period, or alternatively as we all know now you can source the very same calipers from an E38 7/8 series BMW and save yourself a small fortune.
It certainly seems the exact same thing painted red with a Ferrari sticker on it is worth four times the price
I paid £160 for my set, but then a further £150 for a thorough professional inspection by a brake expert, a pressure & dust seal kit, two new pistons (broken by and undisclosed by the seller in his listing), a full flush (found to be full of grit!!), reassembly and final pressure test on Godspeed's pressure rig. You might be able to do things cheaper than me but personally I didn't fancy trusting my life to the fact some random Ebayer promised me he's refurbished my brakes.
My old Ford stoppers were totally shot, I estimated having these old knackerd calipers professionally refurbished would have cost me in the region of £300 including a set of new discs & pads. So using good old man maths the £600 I spent on this upgrade was really just £300. But even at £600 these Brembo brakes are worth every single penny, indeed I'd happily put them up against any of the after market big brake kits offered for our cars at twice that price.
As it stands I like to think I've given 'Ol Gasbag' Ferrari 430 brakes for £300, and when you say it like that it's the bargain of the century!
Highly recommended

Just be careful with the links chaps, these look like 16mm spacers to me and you actually only need 10mm thick spacers to easily clear the Brembo calipers on 16" Imola front wheels like mine.Currently 36% off
http://www.ebay.co.uk/itm/Hub-Centric-4-x-108-63-4...
Do make sure you check the hub-centric lip diameter against your specific wheel centre hole with a set of vernier gauges as different wheels IE... Imolas, Estorils, or other after market alloys may have slightly different diameter wheel hole centres.
Also make certain you are getting fine spline studs as a lot of these kits are sold with coarse spline studs.
Hub-centric spacers are a good idea but plain 10mm spacers will do the job just fine as the hub-centric lip on the TVR hub should protrude enough to give the same wheel centring effect.
Personally I'm not a huge fan of Carlos Fandango wheel spacers full stop as they are not an engineering solution to anything, more of a Max-Power add on used by spotty youfs who know nothing about the effects these things may be having in the steering and suspension geometry.
Steering and suspension geometry is of course a serious science in itself and knowing this I've avoided wheel spacers leaving them to the boy racers to fit on their silly shopping cars with ridiculous body kits.
Unfortunately they are a necessary evil on this conversion and are used to ensure my 16" Imola front wheels clear my super new Brembo calipers, and by rights to keep the same relationship between the front and rear track you'll need to be fitting four spacers of the same depth.
I'm currently only running front spacers because that's just how the job ended late on Saturday afternoon. I calculated I've only increased my front track by 1.5% so I've decided to run the car like this to see how it feels, early indications re it makes fek all difference, indeed the steering and handling feels absolutely spot on still.
I suspect there are more pressing problems with the steering and suspension geometry of a Chimaera, the geometry forced on the car by the use of a front hub/upright originally designed for a family car using a McPherson strut (then adapted by TVR for wishbones) being a key case in point!
My advise on spacers is to be careful blindly following well meaning links posted on these pages.
My recommendation is to measure twice, phone the supplier, and order once!
This is the only way to be 100% sure you're buying the right thing and not just wasting your money

In my opinion the calipers themselves are not really heavy at all, just remove one of the old cast iron mono-piston Ford/ATE calipers for comparison and you'll see exactly what I mean. What are heavy is the new larger discs, at some point I'd like to fit two piece (ally bell & cast rotor) discs as this conversion does add a lot of unsprung weight using standard all cast discs, but for sure it's the discs not the calipers that are the culprit.
I agree with Simon, those calipers from OldPhoneBloke look good to go and somewhat of a bargain, they will also almost certainly work out cheaper than mine, so in the competitive "I did it cheaper than you" world of Penis Heads people will be harvesting their smug points as I type. If you want Brembo discs they are available on Amazon for £100 delivered, I found them after I'd paid £120 so there's a free path to some more points right there. But the truth is you will probably find set of Pagid discs from Euro Car Farts are of equal quality and will be about £70, I've just paid the stupidly cheap price of £42 for a pair of Pagid vented rear discs for my Chimaera and they look just fine to me. Pagid cast discs by the million every year which means super tight quality control, I'm also very confident they'll also be using the right high carbon grade iron.
Pad wise it doesn't seem to matter if you buy Brembo street compound or Pagid road pads they should both be about £35 a set, personally I prefer a good road pad over all these fancy race pads because they tend to work from cold which is nice as crashing first thing in the morning can spoil your day, they also don't make loads of dust like race/track day pads do which can get annoying but not as annoying as the "Squeal Piggy Squeal" noises you must often suffer too. I don't track my car but even if I did my guess is this Brembo conversion will work just fine with road pads, discs function as heat sinks and in this case the discs are flippin huge heat sinks, so any pads will be far less likely to overheat in this setup making a road compound just fine in all but the most extremes of track day punishment.
Re the spacers I would phone the supplier to make 100% sure you're getting fine spline studs, and although not hub-centric the type that's been CNC machined from solid billet are safer than the cheaper extruded type that apparently can crack over time. 12mm spacers were recommended to me but 10mm is plenty to allow my 16" Imola wheel to clear, I would say "less is more" with spacers as they are somewhat of a necessity for clearance rather than the sort of thing you'd fit out of choice.
When spacing the caliper so it's centralised to the disc I found I just needed one M12 X 0.5mm shim washer per bolt, you can buy them in the link below and being just 0.5mm you can add and subtract in a more controlled way than with standard 1mm washers:
http://www.ebay.co.uk/itm/371305099308?_trksid=p20...
I did'nt need the big spacers supplied by OldPhoneBloke in the kit, other than that you just need an M12 tap which may cut the thread ok without the need to ream the hub holes but that's your call, you certainly don't want to shear a hardened tap in there so use plenty of light oil and go half a cut turn in followed by a full turn out to pull out the cast swarf, you may also want to use a 7mm open ended spanner on the tap as access is restricted.
Hope this helps?

Alun, what you've purchased is fantastic and amazingly good value.
Don't expect these Brembos to throw you through the screen on first aplication, that's not the point, in my experience they function just like the originals in 90% of all driving situations which is actually a compliment as you'll enjoy lovely controllable progressive braking.
It's only when you try to stop rapidly from speed or do a medium to slow speed emergency stop that you'll feel the difference, and you will definitely notice a big difference.
I've got no idea how they perform on the track but I'd be surprised if this isn't where these brakes will really shine, I've only done some back road hooning so far and they were absolutely fantastic.
Fit the beggers and cane the arsh out of em till you get that smell of cooked corpse wafting through the cabin, only then will you understand the bargain you've snagged!
Best value is an equation where the price paid meets best performance, and these brakes are exceptional performers at a price point that simply can't be beat.

So looking closely at Daves work,
I think I've got this correct,, please advise if not,
Is this the basic principle.
1, Bracket to hub direct contact using M12 X 1.75 tapped hole and using bolt threaded through and enough to allow a Nylock nut on the back of the hub, 35 mm bolt length? Is that correct?
2, then if mine lines up similar to Daves just one 0.5 mm shim/washer one each bolt to offset the Caliper from the bracket, thus centre ing the Caliper to the disc!
Then depending on wheel offset, I'll need spacers to suit to allow wheel to turn without hitting Caliper
Does that sound about right?
Ta
Yep, sounds about right to me, as others have said you may or may not need spacers with your 17" wheels. No spacers would be my personal preference, do a trial fit and if your wheel touches the caliper use washers to find the minimum spacer depth.I think I've got this correct,, please advise if not,

I've opted for standard nuts to go on the back of the hub bolts and just use thread loc as I feel the heat may effect Nylocks.
This is what I went for in the end, impervious to heat and not as deep as a Nylock either which will only work if the thread of the bolt passes fully through the Nylock nut.http://www.ebay.co.uk/itm/121756587262?_trksid=p20...

I`m just wondering if these massive brakes you are fitting are going to throw the balance out ..The rears are tiny.
No is the answer, but its worth looking at another car using these Brembo GT four piston calipers to confirm.The Ferrari 360 (& 430) both use this exact same caliper, front discs on the Fezzer were 330mm vs the 324 we are using..... so fek all in it. The Ferrari also uses 330mm rear discs vs our 273mm ones, so on the face of it with the Brembo conversion we are under braked at the rear right?
Well no, consider the mid engined 360/430 has a weight distribution of 43% front 57% rear vs the Chimaera 50/50 weight distribution and you can soon see why the Ferrari needs those bigger rear brakes. The 360 brakes are 20% bigger at the rear than to 273mm ones we run, but it needs 20% bigger rear brakes because its carrying more rear weight bias by roughly the same percentage, consistently on the TVR the 324f/273r balance is perfect for the Chimaera's 50/50 weight distribution.
Perhaps a better example is a 2015 BMW Z4 E85 3.0si that while a much heavier sports car overall does share the Chimaera's 50/50 weight distribution, the BMW uses 325mm front discs and 294mm rears so not a million miles off the 324mm fronts and 273mm combo for us with the Brembo conversion.
There is no imbalance with this Brembo conversion, it's more a case that the strange standard 260mm front & 273mm rear setup TVR gave us was imbalanced!
If you'll excuse the punn..... "Brembo adopters are actually just redressing the balance"
