Wilwood GT Series Flared Bell Rotor Hat Front Offset

The Wilwood GT Series Flared Bell Rotor Hat is a front offset rotor mounting hat (also called a rotor bell or rotor hat). It is built for use with Wilwood GT Series two-piece brake rotors. The hat connects the rotor ring to the wheel hub and sets the rotor's position relative to the caliper. Its flared bell design supports large-diameter rotor setups.

Key Features:

• Two-piece rotor design: The separate hat and rotor ring let you replace a worn rotor ring without buying a new hat.
• Lightweight aluminum construction: The hat reduces rotating and unsprung weight compared with one-piece cast iron rotors.
• Flared bell profile: This shape helps with clearance and wheel fitment on front brake setups.
• Front offset configuration: The offset positions the rotor correctly in the caliper for front-axle applications.
• Wilwood engineering: Wilwood is a long-established maker of high-performance brake components for street, track, drag and off-road use.

Pair the hat with compatible Wilwood GT Series rotor rings, mounting hardware and calipers to build a complete big brake upgrade. Several variants are available in this product line, so choose the one that matches your hub and rotor requirements.
