i also have a 4 studs brake system on my r32 as well. braking on those sucks pretty bad esp on high speed, the steering start to shake which indicate the rotors are warping. these brakes are pretty small. i'm planning to drop an rb26 in and i have already got my hands on some r33 gtst type m brake system already. however i only got the rotors, calipers and rear hubs. so i would still need 5 studs front hubs. does anyone know if the z32(300zx) or any other car share the same exact knuckle and hubs as the r32 gtst front hubs?
