Big Brake Hat - Short Offset - Product Description

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.


Shallow 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.

Drilled Steel Rotor Rotors

Steel rotors have applications in all types of motorsports. Steel rotors provide a durable lightweight option in applications where sustained temperatures remain in the low to moderate range, and high heat spikes are only observed on an intermittent basis. This could be anything from a hard stopping drag race car at the end of a quarter mile, or a high speed stock car coming in from a qualifier at a super speedway. Steel rotors can also be found in lighter weight open wheel cars such as sprints and modifieds, and a variety of light weight, open wheel road course racers. A special alloy and proprietary manufacturing processes give these rotors high resistance to thermal distortion with excellent friction and wear characteristics against the pads. View Steel Rotors

SRP Drilled Performance Rotor Rotors

SRP Drilled Performance Rotors feature a specially engineered directional cross drill and face slot pattern that improve brake response and pad performance throughout the entire range of light to heavy braking. The venting and cleaning action of the holes and slots will reduce pad glaze and disperse gasses and heat generated during the pad to rotor interface. The holes and slots also inhibit irregular pad compound build-up on the rotor faces resulting in smoother engagement and improved pedal response in all conditions. The material removed also contributes to lower rotating and unsprung suspension weight. View SRP Rotors
