keeping things light is what I have in mind for the front of my car, especially with a larger motor up front.
with that in mind, i went with the 1990 non turbo 300ZX 26mm aluminum front calipers with fresh rebuilds, and crossdrilled KVR cadmium plated front rotors. it's the lightest combo I can go with and still have a great upgrade from the stock brakes, which can't cope with 170-->60 braking expos easily.
the rear of my car is just good old 1998 s14se rear rotors and stock calipers, no need for anything bigger at this time
stopping a 2400lb car will be very very easy with my setupk, the z32 brakes work excellent.
When the time comes, i'll have AP racing 6 pot with 14.25" rotors up front, and the z32master cylinder with z32 rear brakes

hahaha. probably 2 years from now, I just can't see spending 1800+ ojn bbrakes right now.
