Wilwood Hat-BB Front ..750in Offset 4 x 3.93 - 6 on 6.25in

GT Series Big Brake Short Offset hats are precision machined from premium aluminum alloys for high strength and attention to minimized weight. Hats in this category feature threaded rotor mount holes for use with standard through-hole mount rotors. Threaded hole hats may also be used with T-Nuts or bobbins designed for use with specially machined slotted hole dynamic mount rotors. When used in conjunction with matched Wilwood rotor hardware kits, GT hats provide solid, reliable performance in the most demanding conditions. Short Offset Hats are for narrow space applications with offsets often less than 1.00". They are available for most rotor bolt patterns in a variety of four and five lug wheel patterns.

The Wilwood GT Series Big Brake Front Hat, part number 170-11682, is a precision-machined aluminum brake hat designed for demanding automotive braking applications. Its lightweight construction helps minimize unsprung and rotational weight while maintaining the strength required for reliable performance under high braking loads. This front hat features a short 0.750-inch offset, making it well suited for installations where clearance between the brake rotor, hub, wheel, and suspension components is limited.
The Wilwood 170-11682 uses threaded rotor mount holes for compatibility with standard through-hole mount rotors. These threaded holes may also support T-nuts or bobbins intended for specially machined slotted-hole dynamic mount rotors. When paired with the correct Wilwood rotor hardware kit and a compatible rotor, the hat provides a secure, dependable mounting solution for performance street, track, and competition brake systems.
Designed for specific Wilwood GT Series Big Brake configurations, this hat uses a 4 x 3.93-inch rotor bolt pattern and a 6 on 6.25-inch wheel bolt pattern. Confirm rotor, hub, wheel, caliper, and hardware compatibility before installation. The short-offset design is intended for narrow-space applications and should be installed by a qualified technician following Wilwood system specifications and recommended torque procedures.
