Wilwood Caliper-Forged Superlite 4R-L/H 1.88/1.75in Pistons 1.25in Disc

Wilwood is well-known for making performance brake components, especially for racing applications. This Superlite 4R caliper is a prime example, built for demanding use on the track and for spirited driving. It's designed to be a strong performer, offering improved braking control when you need it most.

What's new with this FSL4R model is the internal fluid porting, which gets rid of the external crossover tubes you'd typically see. This not only cleans up the look but also simplifies the plumbing. It also comes with two bleed screw assemblies, allowing symmetrical piston bore models to be mounted on either side, in either a leading or trailing position. For differential bore models, you still need to orient them correctly for left or right, but you don't have to worry about leading or trailing placement.

This caliper uses a 1.25-inch disc and features staggered piston sizes (1.88-inch and 1.75-inch) for balanced braking force. It's a solid option if you're building a performance brake system and want reliable, race-proven hardware.
