Wilwood Hat-Dynamic BB Front .865in Offset 5 x 4.50 - 12 on 8.75in 170-12624

Wilwood Brake Rotors - 2 Piece 170-12624 Wilwood's new Dynamic Bobbin Mount Hats incorporate a new rotor mounting system that allows the rotors to move independently of the hats as they expand and contract through heat cycles. All thermally generated stress is removed from the rotor attachment points. The rotors stay flatter and run truer. Brake response and pedal feel remain consistent. Pad knock back and rotor drag are eliminated. The hats are no longer distorted by stresses generated by thermal expansion and shrinkage of the rotors. All problems associated with thermal distortion are eliminated. HAT,12x8.75 BC,5x4.50/4.75 MT,.658 OFFSET,2.800 REG,DYNAMIC MT BRAKE ROTOR HAT
