Product Description

The Wilwood 140-14026 Superlite 4R Rear Caliper Kit is a high-performance brake upgrade designed for **1997 through 2013 Chevrolet Corvette** models (both C5 and C6 generations) equipped with **13.00" rear rotors** such as those used on the Z51 and later performance packages. Featuring forged narrow Superlite 4R calipers with four stainless steel pistons and a radial mount design, this kit delivers enhanced clamping force, improved heat dissipation, and better pedal response compared to many original rear caliper designs.

Installation is straightforward thanks to the direct bolt-on fitment using existing caliper mounting points and factory rotor locations. Included BP-20 dual-sport brake pads provide strong street performance with good fade resistance for spirited driving, and the radial mount configuration helps maintain consistent pressure distribution. While brake lines are not included, Wilwood offers specific line kits to complete the installation for both C5 and C6 applications. The kit typically requires **17" or larger wheels** to ensure adequate clearance for the larger calipers.
