cheaper option to buying the full front wilwood big brake kit:
1. wilwood forged superlite internal 4 piston calipers:
Wilwood High-Performance Disc Brakes - Forged Superlite Internal Calipers
2. z33 track rotors + adapter bracket (make your own, or can find online).
after some research, the z33 rotors are 12.76" diameter, and 1.18" thick. this would mean you want one of the calipers that has a rotor max thickness of 1.25 in the link above. the only other decision needing to be made is what you want your overall piston area to be.
