Wilwood Billet Narrow Dynalite Radial Mount Rear Inboard Sprint Kit 12.19in Plain Face Iron Rotor

Wilwood is well-known for making serious braking components for a wide range of racing applications. This Billet Narrow Dynalite Radial Mount Rear Inboard Sprint Kit is a prime example, built specifically for sprint car quick-change rears with 3.00 x 46 splined axles. It’s designed to give you the stopping power and control you need when every ounce of weight and every bit of performance matters on the track.

This kit focuses on reducing rotating weight, which is crucial for sprint car performance. It includes a 12.19-inch vented iron rotor and a specially designed dynamic mount rotor axle clamp. The Dynalite calipers are newly redesigned with Type III hard anodizing for durability and feature BP-40 pads, which work together to offer strong stopping power and consistent fade-free response, even under intense racing conditions. The materials used are chosen for their high durability, long wear, and ability to manage heat effectively, giving you reliable performance lap after lap.

When you open the box, you'll find everything needed to get this system installed: the axle clamp with a dual mount rotor adapter and T-nuts, the radial mount bracket assembly, and all the necessary mounting hardware. This kit is a fully engineered, bolt-on system, meaning it’s designed to integrate smoothly with your sprint car's quick-change rear end.
