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 (343 mm), F50(355 mm), and R35(380mm) 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. 

2. Measure rotor diameter and thickness- front and rear
  • Std Brembo rotors are 324 x 30 mm front
  • Std Brembo rotors are 300 x 22 mm rear
  • Vspec N1 Brembo rotors are 322 x 22 rear


Without doing this, you really are just guessing.

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.

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.
