Wilwood Hat-Dynamic Rear .710in Offset Vette Race 5 x 4.75 - 12 on 8.75in

This Wilwood 170-12985 Big Brake Dynamic Hat, Short Offset, is a crucial component of Wilwood's "Forged Narrow Superlite 4R-QS caliper rear road race kits," engineered to withstand the extreme demands of motorsports competition. Precision-machined from premium-grade aluminum, it offers high strength with low unsprung and rotating weight. Wilwood T-nuts float within the hat, providing true dynamic mounting for standard through-hole mount rotors in 8 x 7.00" rotor mount patterns. This design effectively isolates potential pad engagement harmonics and in-service thermal variations between the hat and rotor, thereby eliminating stress at mount points and preventing rotor distortion. This hat has a 0.703-inch offset and is designed for a 5 x 4.75 bolt circle.
