AFCO 6640137 5/8 Inch Coarse Studs On 5X5 Pattern Long Stud

This rotor combines the strength of a 75-81 Ford-style hub (Granada) with the lighter design of the metric brake rotor for an unbeatable lightweight and durable package. AFCO engineers designed this rotor with the latest CAD software and testing methods. Manufactured to withstand rigorous racing environments, the AFCO Hybrid Rotor uses castings designed and built specifically for racing. It will remove up to 13 lbs. of unsprung weight on the front of your car to improve front to rear weight bias and wheel control. Note: This rotor is not recommended for asphalt applications.
