Wilwood Front Brake Kit with GT 13.06-Inch Rotors and Red Superlite Calipers for C10 Aluminum Modular Pro Drop Spindles, Hubs Separate

Slotted Spec-37 rings and red six-piston calipers provide the front brakes in this modular C10 configuration. Its aluminum hats and BP-10 pads are supplied with the brake hardware, while the hub/spindle unit is purchased separately as part of the correct ProSpindle system. Wilwood Engineering is based in Camarillo, California; Bill Wood founded the company in 1977. Disc brake system design and manufacturing includes calipers, rotors, master cylinders, pressure valves, fittings and brake lines for motorsport, street-performance and specialized applications. Component selection must account for how the complete brake system mounts, operates and balances.
