R34 Gt-R Brakes On R32 Gt-R

[JET200]

Hey guys

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.

Questions

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

Yep done this conversion myself...

Q1. Yes same size bolt m12, but the thread pitch is 1.5mm on brembos, the sumitomo's are 1.25mm, so just get 2 new bolts, no drilling required for rear..

Q2. Yes handbrake cables and set up all bolts on no issues, yes factory front brake lines bolt on, but I went braided lines, I used a set of HEL r32/33 braided lines and it bolted on no issues...

Q3. Yes u can use 32 master cylinder, works fine, I havent had any issues, maybe upgrade to 33/34 later if u got the $$$, but not a neccessity..

Hope this helps, any Q's pm me and I"ll try to help u out...

Andrew,

Did you already installed your BNR34 brakes? I have some that I haven't installed yet. I would love to know what (if anything) went wrong.

You need to bash the backing plates about to make everything fit. I removed them entirely and metal reflective taped over the upper link bush as it is close to the rotor. Also I used the callipers from a 33 and found I had to get some hoses made up as the 33 lines were too short.

2. On the front, do R32 GT-R brake lines bolt straight up? If so will order some R32 GT-R braided lines.

Not sure I had some F40 callipers on the front.

3. Can you get away with using R32 GT-R master cylinder? Or do you HAVE to change to R34 GT-R?

You can get an R32 master cylinder out of an V spec with a larger bore.
