Description

Powerful brake kits for the inboard position on Dirt Sprint cars! Wilwood FNSL6R Sprint inboard brake kits feature a fully engineered bolt-on brake system for Sprint car quick-change rears with 3.00 x 46 splined axles. The kits offer the lowest rotating weight available for Sprint racing via their premium super alloy slotted 12.00 in. titanium rotor and newly designed XRZ axle clamp, 46-tooth spline saver with dynamic-mount rotor adapter plate. These track-proven race kits are highlighted by their Type III hard anodized FNSL6R/ST radial mount calipers that provide superior clamping force with minimal weight. They're equipped with Thermlock insulated pistons for increased heat resistance and BP-28 pads.
