Big Brake upgrade for 15" wheels
Discussion
Spotted this and wondered if anybody was interested in possible group buy,and see if Hans could get the cost down a bit?
Personally would go for groove diskd in the package.

Anything like his other packs it will be a great product that fits really well !
Just need him to do a rear set !
There is this one on fleabay;Just need him to do a rear set !

I'm goingg for these as well. A few hundred quid saving on the hispec price with the obvious cosmetic benefits.
ANy Opinions on x-drilled discs from those who have run them? They look good and lots of exotic metal seems to use them but they don't have a universally good rep?
How big are the calipers ? do you know how good they are ? or is it the TVR Logo luring you in ?ANy Opinions on x-drilled discs from those who have run them? They look good and lots of exotic metal seems to use them but they don't have a universally good rep?
I`m probably want slightly larger discs to go inside a 16" wheel . My Cossie one`s work well but something with 4 pots and lighter .
I hear reports that cross drilled disks are for appearance only, and have been known to crack where drilled. Grooves improve bite under heavy braking, but wear your pads out quicker, so only use them for serious track work, and ventilated disks do the job that you would think cross drilling would do, ie letting heat out.
Oh, I don't know Anthony...
I've had my EBC grooved/dimpled discs on now since I bought the car (previous owner fitted), this being the 4th year of use I have had from that set...
I use the car as my daily - although I have only done one airfield day - and experienced what I would consider minimal pad wear (compared to my other cars), so I don't think on these (light) cars the grooves make a particularly noticeable shortening of pad life on a day-to-day basis...
Conventional wisdom says the fully drilled rotors can crack in some cases - but from what I hear its not a problem with the dimpled variety...???
--- Edited to add: I thought that the cross-drilling was to disperse gas that formed between pad & rotor, leading to brake fade..? ---

Everyone's experience is different Dom, and we all use the brakes differently.
I can really hear my grooved front disks working hard when I do a hard stop on a track day, leaving me thinking "doing their job, but OOOOH me pads!".
I can however say with certainty that in my experience the braking effect of grooved disks over the plain ones of the same size that i had in before is a marked improvement.
I think the grooves do the gas dispelling, if any, but am quite prepared to be educated here.

What about a servo upgrade to go with big beefy callipers?
Its not the servo that ever needs upgrading when larger calipers and discs are fitted, its the master cylinder, but if the new calipers have more pistons than the originals, but are smaller, and the cross sectional area of the pistons combined match the original there should be no problem, I went from the standard griff 500 calipers to brembo 4 piston versions and they work well on the same master.rigga said:

That answers that one then:-) I've often wondered when I read about brake upgrades, it's nice to hear of someone's experience rather than just hear say and speculation.
If anyone is selling a direct upgrade brake system, they should have done all the calculations to determine if it is actually a direct fit, with no detriment to performance, which is kind of not what your after in the first place.
Doing it yourself from parts on the internet, and a best guess, then you're on your own.

Looks very like the hispec offering if so when i upgraded the brakes on nicks orange sc chim hispec built me 300mm rotors fully floating with six pot calipers to just fit inside the fifteen inch wheels pictures are on one of my threads will tru to find them and put them up we also did the rears to get the perfect balance very very good upgrade using an original master cylinder only change to that was i had it machined out and a stainless liner with new internals there is a good load of pics and info on my ( johns chimaera rebuild part two thread page 6)
