Wilwood 170-8320 large brake cap, 0.940 short offset for Mitsubishi Eclipse

Large Brake Hat - Short Offset

GT Series large brake hats with short offset are precision machined from premium grade aluminum alloys for high strength and minimum weight. These hats feature threaded rotor mounting holes, compatible with standard through-mount rotors. They can also be used with T-nuts or brackets designed for dynamic-mount rotors with specially machined slotted holes. When used in conjunction with compatible Wilwood hardware kits, GT hats provide solid and reliable performance in the most demanding conditions. Short offset hats are designed for tight clearance applications, with offsets generally less than 2.54 cm (1 inch). They are available for most rotor bolt patterns in a variety of four and five-lug wheel patterns.

Shallow offset hats are designed for tight clearance applications, with offsets generally less than 2.54 cm (1 inch). They are available for most rotor bolt patterns in a variety of four and five-lug wheel patterns.
