CAMARILLO, Calif. — Wilwood has combined the capabilities of Grand National four piston calipers with lug-drive dynamic-mount rotors in a new road-race package for 2005-2014 Ford Mustangs.

The road-race kit features the high-capacity braking and heat-management of the GN4R/ST caliper coupled with 13.00-inch floating rotors on hats utilizing the simple lug-drive mounting system.

This kit is in full compliance with all current SCCA specifications for American Sedan, and is

also well-suited to NASA classes and other sanctioning bodies requiring four piston calipers and

original-equipment production S197 spindles.

It includes GN4R/ST Thermlock piston race calipers, Spec37 iron alloy GT-48 directional vane rotors and lug-drive hat assemblies, BP-30 race compound SmartPads, braided stainless steel flexlines, caliper brackets, and hardware for a bolt-on, nomodifications-required installation.
