Spacer Kit .482in DL Rear w/Internal P-Brake

The Wilwood Spacer Kit .482in DL Rear with Internal P-Brake (MPN 300-11542) is a precision brake caliper spacer engineered for vehicles running 0.482-inch thick rotors paired with Dynalite II calipers. This spacer kit addresses the dimensional offset between the caliper mounting surface and rotor thickness, ensuring proper brake line geometry and eliminating binding or pad drag. The aluminum construction with black anodized finish provides corrosion resistance in demanding conditions, from street applications to track use.

Spacer kits like this one solve a critical fitment challenge when upgrading brake systems or changing rotor thickness. The .482-inch thickness and 2.5-inch / 2.81-inch mounting hose offset specifications allow the calipers to sit at the correct working distance from the rotor surface. This precision ensures consistent brake pressure distribution, predictable pedal feel, and even pad wear across multiple stopping events. The internal P-brake design accommodates parking brake integration, making this kit suitable for both street and performance driving where mechanical parking brake function must be preserved. Wilwood spacer components are manufactured to tight tolerances to prevent shimming or looseness that could introduce noise or inconsistent braking behavior.

This spacer kit is essential for builders and technicians upgrading brake systems on vehicles where rotor thickness or caliper positioning changes. It's particularly relevant for custom brake installations, brake swap projects, or track preparation where rotor upgrades to 0.482-inch thickness require caliper repositioning. The pair configuration (supplied as a matched set) ensures both front or rear axles receive identical spacing, critical for maintaining balanced braking response. Weighing 0.52 pounds with compact dimensions, installation is straightforward for qualified technicians familiar with brake system assembly and caliper-to-rotor geometry.
