Description

Wilwood Forged Superlite 4 Radial Sprint inboard rear brake kits fully engineered bolt-on brake systems for Sprint car quick-change rears with 3.00 x 46 splined axles. With vented rotors and dynamic-mount rotor axle clamps, these kits offer the lowest rotating weight available for Sprint racing.

The lightweight advantages of Wilwood Sprint rotors are fortified with the high durability, long wear, and superior heat control properties of advanced materials. Redesigned Type III hard anodize forged Superlite 4 radial-mount calipers with BP-40 pads, produce superior stopping power and consistent fade-free response. Kit includes axle clamp with dual mount rotor adapter with T-nuts, radial mount bracket assembly, and mounting hardware.

Wilwood Forged Superlite 4 Radial Sprint inboard rear brake kits are available with solid or slotted curved vane rotors. Choose the kit you prefer.
