WILWOOD ROTOR TOP HAT DYNAMIC LUG DRIVE HUB 170-17745

Wilwood Dynamic Lug Drive Rotor Top Hat, 8 Lug x 7.18 in, 0.730 in Offset

A Wilwood dynamic lug drive rotor top hat fromCA TECH USA, a rotor mounting hub designed for Big Brake applications. Its dynamic lug-drive system lets the brake rotor move independently of the hat as it expands and contracts through repeated heat cycles, removing thermally generated stress from the rotor attachment points so the rotor stays flatter and runs truer with consistent brake response and pedal feel. Spring-loaded replaceable stainless steel inserts protect the aluminium hat from wear, and a single snap-ring retains the rotor without conventional rotor mounting bolts.

Key Features

• Dynamic lug-drive rotor mounting system
• Rotor moves independently of the hat during thermal expansion and contraction
• Removes thermally generated stress from rotor attachment points
• Helps rotors remain flatter and run truer
• Maintains consistent brake response and pedal feel
• Helps eliminate pad knockback and rotor drag
• Prevents hat distortion caused by rotor thermal expansion and shrinkage
• Eliminates bolt-hole alignment issues when replacing rotors on previously used hats
• Spring-loaded replaceable stainless steel inserts protect the hat from wear
• Inserts withstand loading from the stainless steel rotor when brake torque is applied
• Large single snap-ring retains the rotor in the hat
• No need to torque or safety-wire rotor mounting bolts
• Matching discs are additionally drilled to reduce unnecessary rotating driveline mass
