2009+ Audi A4 SP Performance Front Cross Drilled Brake Rotors ZRC Finish (2)

SP Performance Cross Drilled Brake Rotors have a design that offers the best results possible in cooling and venting brake dust and moisture. Unlike our competition there is no sharp edge on our chamfer. This is accomplished by the use of an outer radius curve rather than a countersink. With the radius curve, or "Sinusoid Curve", it virtually eliminates an edge on the surface of the hole. This smooth surface also makes the rotor more pad friendly by reducing the wear of the pad caused by the friction scraping against a sharp edge.

SP Performance Cross Drilled Left & Right Brake Rotors With Standard Gray ZRC Finish:

All rotors are provided with our gray ZRC coating. It provides long-lasting protection against corrosion in the most hostile salt-water environments. After being applied, ZRC provides the highest level of galvanic protection. The film of ZRC is conductive. After the coating heats up during use, it bonds permanently to the metal surface. It will not allow the metal to corrode, even when the surface is scratched.

Features:

• Optimized air circulation for increased cooling. 
• Increased pad bite.
• Vents bake pad gases.
• Improved wet weather braking.
• Reduced fade.
• Increased Safety and Reliability.
