Wilwood Billet Narrow Dynalite Radial Mount Inboard Brake Kits
Wilwood Billet Narrow Dynalite radial-mount inboard brake kits feature a fully engineered bolt-on brake system for sprint car quick-change rears with 3.00 in. x 46 splined axles. Available in several choices, the kits will have titanium, Super Alloy, or steel .810 vented or solid discs and a newly designed dynamic mount rotor axle clamp, providing the lowest rotating weights 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 the advanced materials used. The billet Dynalite radial mount 4-piston calipers are Type III Anodized and will be fitted with composition metallic or BP-40 pads to produce superior stopping power and a consistent fade-free response. Kits will also include an axle clamp with a dual mount rotor adapter with T-nuts, radial mount bracket assembly, and mounting hardware. Choose the preferred kit for your braking needs.
