Wilwood Narrow Superlite 4R Rear Kit 12.88in Drilled Speedway Eng Floater w/ New Style End

This is the Wilwood Narrow Superlite 4R rear big brake kit, designed to be a complete solution for popular muscle car rear axles that need a parking brake function. It includes everything you need to significantly upgrade your car's stopping power, especially when paired with a front big brake kit. The FNSL4R four-piston calipers, 12.88-inch two-piece rotors, and high-performance BP-10 compound pads work together to give you balanced braking for custom builds, show cars, and high-performance street machines.

What sets this kit apart is the integrated shoe system for the parking brake. It's neatly hidden within the caliper assembly, providing a clean look without sacrificing holding power when the parking brake is engaged. The rotors in this kit are drilled, which helps to dissipate heat and reduce weight compared to solid rotors. The Speedway Engineering floater design allows the rotor to expand and contract with heat without inducing stress, which can help maintain consistent braking performance and rotor life under hard use. Wilwood offers optional caliper finishes and rotor designs, so you can personalize the look and performance to match your specific build.

When installing a kit like this, it's important to follow the manufacturer's instructions carefully. This kit is designed to be a comprehensive upgrade, but you may want to consider checking your brake fluid type and condition, as well as ensuring your master cylinder is appropriately sized for the increased braking force. This kit is a solid option for anyone looking to build a serious performance vehicle.
