Wilwood 170-0635 Hat-Pantera-Std Disc Brake Rotor Hat 1.38" Offset

The Wilwood 170-0635 Hat-Pantera-Std is a precision-machined disc brake rotor hat featuring a 1.38" offset, designed for use with Wilwood's threaded-hole, 8 x 7.62 bolt circle mount rotors. Part of Wilwood's Pro Street Series Fixed Mount Rotor Hat lineup, this hat delivers a long-standing reputation for exceptional fit, performance, and durability in both street and competition applications.

Manufactured from premium-grade aluminum alloy, this rotor hat offers an ideal combination of high strength, reduced unsprung weight, and show-quality surface appeal. The straight bell construction features a flanged rotor mount ring with through holes, maximizing radial clearance between the caliper body and the hat — a critical advantage when fitting large-diameter calipers inside compact wheel packages.
