Wilwood Caliper-BNSL4R-Red 1.25in Pistons 1.10in Disc

What you get with this Wilwood Superlite caliper is a forged billet narrow Superlite (FNSLR) caliper in a striking red finish, featuring 1.25-inch pistons and designed for a 1.10-inch disc. This caliper series has been a go-to for years in competitive racing, from short tracks to late models, and has also found its way into demanding road-race, off-road, and rally applications. It's a well-built piece that represents an updated approach to Wilwood's popular Superlite line.

The FNSLR caliper builds on the legacy of the Superlite series by incorporating new technologies that bring substantial improvements. You'll find it offers better strength and increased fluid volume displacement compared to older designs, all while keeping the weight down to around 4.40 pounds. This caliper is specifically the FNSL4R model, which is notable for including piston dust boots, often a requirement for export markets but beneficial for keeping debris out of the piston bores in any application. It's a solid choice if you're looking to upgrade your braking system for more assertive driving.

When considering a brake upgrade like this, remember that calipers are just one part of the system. Ensure your rotors, pads, and brake lines are also up to the task to get the most out of this performance caliper. Wilwood is known for its focus on braking performance, and this caliper is a testament to that.
