300zx brake sizes? Help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

hey guys.

my rotors are warped as hell. I have a set of 300 zx brakes on my s13, but i dont know if it is from a 300zx or a 300zx turbo. I heard that theres a slight difference in the sizes for the fronts. If so, is there a obvious way to tell? please help me out. dont know which one to order. thanks.

measure the thickness of the rotors.

there are 26mm and 30mm rotors, the 26mm were only used on 90 NA 300ZX the rest used 30mm.

^~~~I thought 26mm where in a few years?

pretty easy to figure out if the are light and aluminum they are 26mm and if they are heavy and iron they are 30mm. or measure your current rotors

26mm were only one year. there were also 30mm aluminum calipers so AJ's tactic won't work.

Derk had it right off the bat. measure the rotor and be done with it. 30-28mm is a 30mm rotor, 26-24mm is a 26mm rotor. (lower number is the lower wear limit which the rotor could get to if it's old)
