Stoptech High Carbon Premium Drilled Rotors 330mm (Rear Left) Audi B8/8.5 A4/A5/S4/S5/Q5/SQ5, B9 A4 & C7 A6/A7

StopTech 125 Series High Carbon Alloy Brake Rotors contain an advanced metallurgy that greatly reduces the possibility of pad squeal especially with higher friction, European style brake pad compounds. Proprietary Molybdenum and Chromium alloys resist rotor cracking during high performance use or repeat stop situations. This alloy also increases the friction couple improving brake performance and stopping power. Increased Chromium and Carbon content is also more resistant to oxidation.

• Symmetric split core castings for Increased strength and stability
• Black E-Coat anti-corrosive coating protects the cooling vanes and mounting surfaces from rusting prematurely
• Double disc ground friction surface finish
• Mill balancing ensures smooth operation at all speeds

StopTech parts High Carbon Alloy Brake Rotors feature a double disc ground finish which virtually eliminates run out and any disc thickness variation issues. Double disc grinding also produces a non-directional finish for improved rotor and pad break-in. The surface Roughness production standard for Centric High Carbon Brake Rotors: RMS=64.3 or Ra=1.6 micro-meters (63 micro-inches).

StopTech Parts High Carbon Alloy Brake Rotors feature our exclusive black E-Coating on all non-friction surfaces. E-Coating is an advanced electro-statically applied finish that has been engineered to withstand 400 hours of salt spray testing without corroding.
