Product Details

Wilwood GT Series brake rotor hats are precision-machined aluminum rotor hats for two-piece brake rotor assemblies. They are used in high-performance street and racing brake systems. The hat is the mounting bell that connects the brake rotor ring to the wheel hub. Offset is the key dimension for setting rotor position and caliper clearance in your brake setup.

Key Features:

  • Premium aluminum alloy construction: Machined for high strength while keeping weight to a minimum.
  • Threaded rotor mount holes: Designed for use with standard through-hole mount rotors.
  • Dynamic mount compatibility: Threaded-hole hats can also be used with T-nuts or bobbins made for specially machined slotted-hole dynamic mount rotors.
  • Multiple offset styles: The GT Series includes short and shallow offset designs for narrow-space applications, as well as other offsets for different brake setups.
  • Wide range of configurations: The line covers many rotor bolt circles and wheel stud patterns for street, drag and road race use.

When paired with matched Wilwood rotor hardware kits, GT Series hats give you solid, reliable performance under demanding conditions. Choose the variant that matches your rotor bolt circle, wheel stud pattern and required offset.
