Wilwood has engineered this SLC56 front caliper to be high performance and custom replacement for Corvettes and hot rods using Corvette suspension. These calipers add high-tech styling and provide the positive response & balance pad loading provided by a fixed mount, four piston caliper. These front calipers are direct bolt-on replacements for the OE calipers on all models of 1997-2004 C5's and all base model 2005-2013 C6's using 12.8" diameter front rotors. You won't have to worry about fitment as the calipers attach directly to the Corvette spindle without the need for brackets or adapters and accept all types of OE banjo bolt style brake hoses.

The SLC56 front caliper is based on the top performing Superlite caliper series. These front calipers feature an ultra-high strength forged aluminum body, stainless steel pistons, internal bore seals, internal piston damping springs, stainless steel bridge wear plates, and a single screw bleed system. These front calipers accept the same type 7416 16mm thick brake pads as used in all Superlite series calipers. 


The OE piston volume is matched with these SLC56 front calipers. This makes the calipers fully compatible with the output of the OE master cyluinder and ABS system. In addition, front to rear brake bias and pedal travel remain as stock. If you're doing a custom build, the caliper volume is also easily matched to other styles of manual or power brake pedals with proper master cylinder sizing.


Internally, all surfaces and passages are anodized to provide corrosion resistance with a durable wear surface for stainless pistons inside. Externally, these front calipers are finished with a high gloss protective powder coating process that is both brake fluid and heat resistant for extra corrosion resistance. These calipers will look as great as they will perform for many miles to come.
