R32, R33, R34 Brembo Brakes : Brake Upgrades : Brake Downgrades

Brakes:  Overlooked by most.  Sort of important if you want your car to stop.  Also important, tires, but this post is about brakes. We have an entire post on the Sumitomo brakes that came standard on the R32 GT-R.  I realized that I have not put much specific brake information about the Brembo brakes that come on the R32 Vspec and Vspec II , R33, and R34 GT-R.  There are also upgrade brake kits such as the F40 (332 or 343 mm), F50(355 mm), and R35(380mm 09-11, 390mm 12 up) calipers and rotors, which are popular swaps for these cars. 

How to Identify Your Brakes: 

This is important. With cars that are over 25 years old, there is no telling what brakes are actually on the car. Even though it "should" be something, or seems like something, it might not be. 

1. Remove brake pad and trace the outline from one pad.  This will give you a shape that almost any decent race brake shop can identify.  Friction Material Standards Institute number. FMSI number

2. Measure rotor diameter and thickness- front and rear

Without doing this, you really are just guessing. 

R34 Brembo Brakes (Gold) 4 pot/piston. 
The R32 Vspec and Vspec II got a brake upgrade in the form of Brembo calipers, and larger rotors front and rear.  324mm x 30 mm Brembo front vs a 296 mm x 32 mm Sumitomo/Nissan front. 

From the now defunct Webbers RB Guide page. 

  • Std Brembo R32/R33/R34 rotors are 324 x 30 mm front
  • Std Brembo R32/R33/R34 rotors are 300 x 22 mm rear
  • Vspec N1 Brembo R34 rotors are 322 x 22 mm rear

Project Mu Brakes

Fully custom color matched rotors and calipers

There are lots of companies out there that make "brake upgrades" for cars. 6,8,12 piston. Some other crazy things. Not much impresses me.  If its not Brembo, AP, Alcon, or Performance Friction, I don't want to have to deal with it. Endless and Project Mu have some decent stuff, but the prices are fairly over the top  The right tire, driver, brake fluid, and brake pad go a long way. More than most drivers will ever need.

Not all standard R34 GTR use same size rear rotors. The series 2 R34 GTR have N1 rear brakes and therefore use 322x22mm rotor.

The series 2 R34 GTR (non-vspec) use N1 brakes as standard. Therefore, those are 322mx22mm rotors in the back for Aug 2000+ R34 GTRs.
