Product details
For a brake system using a 0.81-inch-wide rotor, this Type III anodized Wilwood Forged Superlite 4R provides 4 pistons with 1.88/1.75-inch bores. Right-hand mounting is specified. The caliper attaches on 5.98-inch radial centers.

Internal fluid passages and radial mounting distinguish this four-piston Superlite. The selected piston design and bore sizes must match the brake balance calculation; they are not interchangeable merely because the mounting centers agree.
Fitment & Compatibility
Check pad depth against the rotor’s usable friction annulus. Rotor-hat clearance, mounting offset and the wheel’s inner profile must also be checked with the caliper drawing.
This listing covers one caliper. Match the brake pads, rotor, hose and mounting arrangement to the complete brake system.
