Description
Built for Extreme Braking Demands. Double the drilling, double the cooling. SP Performance Double Drilled & Slotted rotors carry two sets of precision drilled holes with machined slots between them for the most airflow, heat dissipation and debris removal in the line. Every hole carries the exclusive Sinusoid Curve Chamfer, which improves air circulation, removes sharp edges and reduces stress around the hole. Built for aggressive driving where heat and pressure never let up. This set covers the front axle with two rotors in red zinc coating. Fits 1991-1994 Chevrolet C3500HD. SP Performance is a women owned business in Lawrenceburg, Indiana. Our rotors are machined in house on CNC equipment, inspected before they ship, and finished in our ZRC coating in grey, black, silver or red for corrosion resistance and a clean look.
