This aluminum front kit is light and stops amazingly well. The key is the coating on the rotor and the pad/rotor combination. We used the same rotor for 2 years on my daughter's 305 car. Includes new Wilwood hard anodized caliper, 10.95" drilled aluminum rotor, 2 pads, rotor bolts, caliper bracket, and caliper mounting bolts. Genuine Wilwood parts.
