R34 GT-R brakes on R32 GT-R. Who's done it?
Posted 07 March 2012 - 08:38 PM
I've spent the last hour looking through old threads, so I have searched but just want to ask some questions to people that HAVE put R34 GT-R brakes on their R32 GT-R. No need to sell me some other option as already have the calipers, rotors and pads.
I know you need to re-drill the R32 GT-R hubs to accept the 14mm bolts of the R34 GT-R caliper. That seems easy enough. Just use a drill with the right size drill bit.
1. Do the rears just bolt straight on? Does the R32 handbrake set-up still work fine inside R34 rotor? Do you use the R32 GT-R brake lines or R34 brake lines?
2. On the front, do R32 GT-R brake lines bolt straight up? If so will order some R32 GT-R braided lines.
3. Can you get away with using R32 GT-R master cylinder? Or do you HAVE to change to R34 GT-R?
Any help would be appreciated. Better to go into it armed with correct knowledge than finding anything out the hard way

I haven't done this to my BNR32, but from what I know the masters are different between the brembos and non. BM50 for std BNR32 and BM57 for brembo. If your std BNR32 has the brembos factory, then you're good. If not the difference is bm50 = 25.4mm and BM57 = 26.9mm. Measurement is in master cylinder diam. Negligible really.
I would go for Brembos if you can find a good set second hand. The size is probably bigger!

Will try with same master cylinder first and see what happens. Just wasn't to see who has actually done it.
