The engineers at Premier Tuning Group have developed and designed the perfect gear ratio for your high powered C63. Our 2.65:1 Ratio Ring & Pinion Set are a taller gear as compared to your 2.82:1 (sedan) or your 3.06:1 (coupe) which allows your higher power C63 to stay with in the powerband for both quarter mile racing and better 60-130mph or 100-200km/h times.
PTG can also supply other ratios so that you can finely tune how your car behaves, allowing your AMG to fit your use exactly whether you're looking for response, road racing, daily driving, or more.
Changing rear gear ratio requires ECU tuning for the vehicle to function correctly.
NOTE: This item is made to order and has a lead time of 2-3 weeks in most cases. Please be sure to specify your vehicle when ordering.
