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 kit (MSRP: $3,025.39) features the high-capacity braking and heat-management of the GN4R/ST caliper coupled with 13.00” 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 OE 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, no- modifications-required installation.
