Wilwood 170-16203 Big Brake Dynamic Lug Drive Hat, Short Offset — Corvette C5/C6 FNSL4R Rear

Wilwood 170-16203 Big Brake Dynamic Lug Drive Hat, Short Offset

Forged aluminum rotor hat with a Type III hard anodized finish, used with Wilwood’s Dynamic Lug Drive mounting system. Spring-loaded, replaceable stainless steel inserts in each lug-drive slot protect the hat from wear as brake torque loads the rotor against it. A single snap-ring retains the rotor — no bolts to torque or safety-wire, and the rotor is free to expand and contract independent of the hat through heat cycles. As used in the Wilwood 140-16208 Forged Narrow Superlite 4R Rear Kit for the Corvette C5/C6.
