Any Problems Running R34 Brembo Fronts With R32 Gtr Rears

[Swiper the Fox]

Looking at selling R34 GTR front calipers and rotors to a friend (Bezerkley Bumblebee car) and he is worried they will not have correct braking bias due to the piston area...can anyone give their findings/experiences so he can be assured he's not wasting his time or $$. The rears are STD Sumitomo calipers and rotors.

thanks in advance

no problems at all, the brembo rears are very similar piston size to the standard rears so their balance and feel is fine.

we ran with brembo fronts and 32 gtr rears for about 18 months until a set of the rears came up (they are much more rare than the fronts).

Sweet i knew you would be the man to clear that up for him...as i told him that that was your race set up...ill ring him and let him know.

Whats the difference between the Brembo's and Sumi's in rear pad size?

thanks

Trust the man - I fitted those brakes to the rear of the car - lol

thanks to the helpful guys at bendix.com (but be careful they show the 32 caliper as being on the 33 and 34 as well....)

32 rear info

33/23 (brembo) rears

comparison of pad size

to me the rears aren't worth the trouble to upgrade, the caliper is about 10% bigger and the pad maybe 20% bigger. Much easier just to put a more agressive pad in the rear, they don't work that hard in the standard setup anyway.

Hey Paul

Just to give you some perspective, I'm running these on the front of my 32 GTR with the std Sumitomo rears & master cyl with no probs. I think from memory the 8-spot's are around 13% larger piston displacement compared to the Sumitomo 4-spot's that came off so it's amazing what you can get away with sometimes.

BTW the pic is different to mine but the specs are identical (a mate of mine right near you has the same pictured set on his 32 with Brembo 4-spot's on the rear w/pedal box, split masters etc)- I bought mine from DoughBoy a few yrs ago so maybe you've already seen them at one time.....

I DID have the specs for all the Skyline brake components here somewhere but I can't lay my hands on 'em right now, I orig stole 'em from Roy anyway so if need be shoot him a PM. BTW it's good to see that both you & Duncan have put your shit behind you (WTF it was). I might not say much on here, but I see a lot

Cheers guys
