Hi everyone, I was fortunate enough to get a hold of a complete set of R34 GTR Brembo V.spec brakes! My original idea was to buy an STI or an EVO caliper, adapter brackets some kinda brake line conversions (braded lines) and hope that Evo rotors will be precise fitment! I never went with that idea just because calipers alone were costing too much and I never seen them around for a good price! Im also VERY GLAD that i went with R34 GTR calipers vs other Brembo caliper and I will explain why later on in the thread. I will start from the back, just like I did on my car!
Here is few threads that I was looking at while considering my brake upgrade:
STi Brembos on GTR
Ctsv Brembos. Anyone tried?
Below is a comparison of R34 regular caliper and R34 V.spec caliper:
No matter how hard i looked i coudn't find an answer how V.spec uses 322 rotors, some say they have different spindle some that they have different caliper some people say that both of this items is different!
You can see how the mounting holes distance is identical, along with holes diameter (I did check it on my R32 spindle and they do fit, Identical, interchangeable with no modifications) so they are all interchangeable on any "R" spindle. The difference is in the caliper "height" if you wish. Pads are the same so is the line threading on the caliper.
R34 on R32 spindle
R34 V.spec on R32 Spindle
R34 V.spec rotor dimension is 322x30mm (On the Left) and R34 Rotor is 300x30mm (On the Right). The V.spec rear rotors suppose to be almost identical to a Z33 Brembo package rear rotors, but I CANT confirm this because my rotors were in practically brand new shape so I didn't have to order new ones.
Comparison Between R32 and R34 rotor:
Comparison Between R32 and R34 V.spec rotor:
R34 and R34 V.spec calipers bolted down by 10mm bolts with 17mm head compare to 10mm with 14mm head on R32 (last one one the right)
In order to fit larger rotors (not sure if you have to do it if you are using regular R34 brakes) you have to cut dust shield edge, and to make it pretty shave all the sharp edges! Also, adjust E-Brake to a new rotors.
Here is comparison of R32 to a V.spec caliper
In order to make it fit on the stock R32 GTR lines you have to use stock R32 brake line support braket
You will have to redrill it to make it work on Brembo caliper:
Do this on both side and you will have upgraded Brembo brakes in the rear!)))
