The S197 Mustang (fifth generation) has plenty of power and handling for SCCA and NASA competition, and now Wilwood offers a race-proven big brake kit to match. The GN4R lug-drive kit is the ultimate four piston brake package, with floating 13.00" x 1.25" Spec37 iron rotors and Grand National stress flow forged aluminum calipers developed for stock car racing.

Wilwood's dynamic mount system removes thermal stress from the rotors and hats, allowing rotors to run longer and truer, while 48 directional vanes shed heat quickly. The calipers feature a rigid design and two central bridge bolts for reinforcement. Four large pistons comply with class rules and feature Wilwood's Thermlock thermal barrier for reduced heat transfer.

MSRP starts at $3,025.39
