Reyland Motorsport 2-piece discs for V8V

[Nigel_O]

My front discs had a very slight judder on them when I bought the car. Yesterday, my son and I had a 'spirited' drive round North Wales and now I have a much greater judder....

I recall reading a comment that the V8V front brakes don't get a lot of ventilation, so it's not surprising they can warp. Over my many years with Fiat Coupes (also suffer from poor ventilation), I went through dozens of discs until I bit the bullet and fitted 2-piece Brembos.

I've seen Reyland Motorsport 2-piece discs for the Vantage at about £775 (or a bit more to go up to 370mm or 380mm, which I don't see the point of)

Has anyone tried them?

You’re not wrong about the heat thing. I think out of all the cars I’ve owned the vantage holds heat in the brakes like nothing else I’ve had.

They’re good brakes to be fair, but they do get very hot very quickly and take an age to cool down.

Could really do with some ducting

No experience of Reyland. I have a 4.7 with the later 6 pot brembos, and fit a front pair from RB Racing rotors earlier this year, along with Porterfield pads. Really impressed so far, no squeal, near zero dust, great feel.

I have no evidence, but it looks like RB rotors are the same as Reyland - they both offer exactly the same discs with the same choice of groove patterns

[bogie]

Maybe they use the same supplier... for some custom machined bells in whatever finish you specify plus the discs in 3 variations for 1/2 price of OE discs.

Reyland buy blank castings and machine them to whatever spec you need.

3 things to bear in mind with reyland rotors. They are not balanced which may or may not matter to you. They are slightly heavier than a equivalent AP rotor of the same spec. The internal vanes are not swept, they are straight (AP are swept as I am sure brembo are). Again, those thing might not matter but are worth bearing in mind.

I have gone from AP to reyland on my car and for the money I can't really fault them so far. Especially at nearly £200 a pair cheaper.

Excellent information - thanks

Great timing with this post as I am needing new discs for MY2010 V8V.



What are the thoughts on the 370 or 380mm solutions with the standard 4 pot front calliper. I have had the pedal go soft a few times, normally really enthusiastic driving on mountainous roads.

Secondly which style, I'm thinking Type III or Type V probably Type V. Alternatives include Jhook, straight slot or drilled. (Concern around drilled is always going to be cracking.)

Jhook


Straight slot


Type V


Type III

Can you even fit 380mm with the 4 pot calipers ?

Yes, with a bracket/spacer to move the caliper out by 12.5mm

I fitted 410mm to mine with 6 pots and the bracket from a DBS

Reyland can't get blanks for some time, so I've just bought discs from RB Rotors

I absolutely convinced myself that the standard 355mm disc would be just fine for a road car, so when I spoke with Jamie at RB yesterday, I caved in instantly and bought the 380mm conversion.....

[IainWhy]

personally i found the standard brakes to be complete and utter toss. 380mm will give you some more thermal mass but if you want actual performance from them they need a much more serious pad and better ducting as well as the additional torque of the 380mm will simply exacerbate the fade.

Your mileage may vary of course, but floppy road pads like porterfields etc wont cut it if your pressing on imo

Out of interest does this mean you opted for new 6 pot callipers too? Or a spacer bracket for your existing 4 pots? Either way I would be really interested to see how you get on with these.

Just a spacer for the 4-pots - budget won't run to new calipers

I'll see how the Porterfield pads go - the car won't be going anywhere near a track (I have a Westfield for that) but it will be subjected to the occasional bit of enthusiastic driving on the road. If the Porterfields aren't up to the job, I'll move to Pagid RS29 which I used to have on my Fiat Coupe (which was far faster than the V8V, but a fair bit lighter).

@Nigel_O

In your chat with Jamie what was it that made you upgrade to the 380mm discs and which disc face type did you go for?

[Nigel_O]

Soooo irritating when a plan doesn't come together....

Discs arrived from RB Rotors in very good time and pads from DAE were even quicker. Weather is good enough today for fitting them so got everything ready, jacked the car, removed the wheel and then couldn't get the disc retaining screws out. I don't have a T40 impact bit and I ended up twisting my non-impact bit. I also tried the caliper bolts and they weren't going anywhere either.

So - all back together and dropped off at my local KwikFit (I know the lads well - they'll look after it), so that they can get some proper tools on it.

Discs look good though



I know 380mm is overkill, but the difference in cost was minimal (in the greater scheme of things) and I just fancied them.
