Wilwood Caliper-Forged Superlite 1.38in Pistons .81in Disc

If you're building a track car or a serious performance street machine, you know how critical reliable braking is. The Wilwood Superlite caliper series has been a go-to for years in competitive motorsports, and this FSLI model is an updated take on that proven design. It's built for the demands of short track, late model, modified, and open wheel racing, but it's also a popular choice for spirited road-race, off-road, and rally applications where consistent stopping power is key.

What sets this FSLI model apart is its internal fluid porting. Wilwood redesigned the caliper to move the fluid crossover internally, getting rid of the external tubes that could be a weak point if damaged. This also means you get two bleed screw assemblies, making these calipers symmetrical so they can be mounted on either the left or right side, in a leading or trailing position. The forged body construction means it's well-built for the stresses of hard braking.
