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
- 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
- F40 Front and Rear rotors are 332 x 32 mm
- F50 Front rotors are 355 x 32(34?) mm
- R35 Early - Front 380 x 34 mm
- R35 Late - 390 x 32.6 mm (they went thinner)
- R35 rear - 380 mm x 30 mm
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.
