Wilwood GN4R Lug Drive Race Front Big Brake Kit; Anodized Gray Calipers (05-14 Mustang)

Description

PREMIUM BRAKE SYSTEM. The Wilwood GN4R Lug Drive Race Front Big Brake Kit with Anodized Gray Calipers is engineered for road race competition requiring four-piston calipers. It delivers superior stopping power and control by combining advanced calipers and high-capacity rotors, enhancing performance and safety on the track.

CONSTRUCTION AND APPEARANCE. The calipers feature a forged aluminum body with a durable Type III Mil-Spec medium gray hard anodized finish for increased wear, abrasion, and corrosion resistance. The rotors are constructed from Spec-37 iron with a directional vane design, dynamically balanced for smooth operation, and paired with aluminum rotor hats finished in matching anodized gray.

INSTALLATION. This brake kit is designed for factory disc spindle fitment and mounts radially for ease of installation without the need for drilling. Wheel clearance should be verified due to the minimum 17-inch wheel size requirement.

APPLICATION. Fits 2005-2014 Mustang models specifically; wheel clearance should be checked to ensure compatibility, as some 18-inch wheels may also fit.
