Wilwood HD Series Drag Race Rotor Hat Offset

The Wilwood HD Series Drag Race Rotor Hat is a fixed mount aluminum brake rotor hat (also called a rotor bell or rotor mounting hat). It is made for drag racing and high-performance disc brake setups. Wilwood's HD Series fixed mount hats are known for fit, performance and durability. They are offered in a range of offsets to suit different wheel and brake packages.

Key Features:

• Premium aluminum alloy construction: The hats are precision machined from high-grade aluminum alloy. This gives high strength, low weight and a show-quality appearance.
• Fixed mount design: The hats have threaded rotor mount holes. They are meant for use with standard through-hole rotors.
• Straight bell construction: A flanged rotor mount ring and straight bell give the most radial clearance between the caliper body and the hat.
• Versatile applications: Wilwood uses HD hats in many of its racing disc brake conversion kits. They cover applications from an OE four-lug axle shaft to a Grand National stock car racing hub.
• Multiple wheel patterns: Many hats are multi-drilled for several lug patterns, so one part works with more than one wheel.
• Weight savings: The aluminum construction cuts rotating weight compared with heavier hat materials. Less rotating weight helps in drag racing.
