Wilwood Caliper-Forged Superlite 4R 1.38/1.38in Pistons 0.81in Disc

When you're looking to significantly improve your vehicle's stopping power, especially for demanding driving conditions, the Wilwood Forged Narrow Superlite 4R (FNSL4R) caliper is a solid choice. This caliper builds on the well-known Superlite series by adding radial mounting, which makes it much simpler to adapt to different setups and allows for precise alignment over the brake disc. It brings Wilwood's advanced brake technology to a caliper that generates substantial stopping force, suitable for a wide variety of vehicles that need more than stock braking performance.

The FNSL4R caliper is forged, meaning it's made from a solid piece of metal that's heated and shaped under pressure. This process results in a very strong and rigid caliper body that can handle the high forces generated during hard braking without flexing. Inside, it features dual pistons, each measuring 1.38 inches, designed to work with discs that are 0.81 inches thick. This combination is engineered to provide consistent and powerful braking, helping you slow down effectively when you need it most.
