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.Flared Bell Hats are generally used with rotor mount bolt circles of 8.38" and larger. Offsets range from 1.88" to 3.00" for rotor diameters 12.19" and up.
