Product Details

This is the Wilwood Forged Billet Narrow Superlite 4R (FNSL4R) brake caliper in red, featuring 1.25-inch pistons and designed for a 1.10-inch disc. The Superlite series has long been a go-to for competitive racing, including short track, late model, modified, and open wheel events. It's also found its way into demanding road-racing, off-road, rally, and spirited street driving applications where reliable stopping power is crucial.

Wilwood has updated this popular caliper with their Forged Billet Narrow Superlite design. By applying new technologies, they've achieved notable improvements in overall strength and fluid displacement, which translates to better braking performance. This particular FNSL4R model is unique within the Superlite line as it includes piston dust boots, often a requirement for export markets, helping to keep contaminants out and maintain consistent operation.

It's a well-built component designed for drivers who push their vehicles hard and need braking hardware that can keep up. While this caliper is designed for performance, it's always a good idea to consult Wilwood's technical documentation for specific installation requirements and compatibility with your brake system components.
