Description

The Wilwood SL6R 13" Front Big Brake Kit is engineered to deliver superior braking performance and enhance the appearance of your 1985-1987 Chevrolet Corvette. This comprehensive kit replaces your factory front brake components with a Forged Narrow Superlite 6R six-piston caliper and a 12.88" rotor, significantly increasing stopping power for show cars and high-performance street/track applications. Additionally, two bottles of Wilwood's specially formulated Hi-Temp° 570 Racing Brake Fluid are provided. This fluid boasts a minimum 570°F dry boiling point, crucial for withstanding the extreme heat generated during demanding driving conditions. Installation of this big brake kit may affect wheel offset and will necessitate the use of 17-inch or larger wheels for proper caliper clearance. It is strongly advised to consult the provided wheel clearance diagrams to ensure compatibility with your specific wheels before ordering. All returned orders are subject to a restocking fee, underscoring the importance of verifying fitment prior to purchase. The black caliper finish provides a sleek, performance-oriented look. Optional caliper finishes and rotor designs are available to further personalize the braking system's style and performance.
