Wilwood Narrow Superlite 4R Red Rear Caliper & Bracket Kit for Select 1997-2013 Corvette & Cadillac XLR (140-14026-R)

Fits select 1997-2013 Chevrolet Corvette (C5/C6) and 2004-2009 Cadillac XLR models equipped with or updated to 13.00-inch rear rotors.

The Wilwood Narrow Superlite 4R (FNSL4R) rear caliper kit is engineered to provide professional-grade stopping power and thermal stability for C5 and C6 platform vehicles. These four-piston radial mount calipers replace the factory sliding units, mounting directly to the stock locations via the included high-strength brackets. Designed specifically for use with 13.00-inch rotors (such as those found on 2005-2009 C6 Z51 models), this kit maintains full compatibility with the OE master cylinder output and ABS system for a confident, balanced pedal feel.

Constructed from forged aluminum, the Superlite 4R features a center bridge reinforced body to minimize caliper deflection and fluid volume displacement under heavy braking loads. The kit includes Wilwood BP-20 Smart Pads, a dual-sport compound that offers quiet, low-dust operation for daily driving while providing the high-temperature fade resistance required for autocross and track days.
