AMG already does an incredible job adding performance and power to the Mercedes-Benz lineup. The automaker's in-house tuner is without a doubt amazing at what they do. Their list of accomplishments is too long to go over. And now, tuning firm Wimmer has decided to add their signature to the C63 AMG sedan. They began by reworking the heads, added even more aggressive camshafts, a larger down pipe, and a higher flow catalytic converter.
They also installed a stainless steel exhaust system. All told, the car now produces 601 hp and 531 lb-ft of torque. To the satisfaction of many, Wimmer has also removed the top speed limiter. It will now hit 203 mph. Wheels have also been swapped out for a new set of 19-inch alloy wheels with Dunlop tires. As it usually goes, these modifications aren't cheap, with the engine work costing about $28,000. If you want the suspension work done, that will cost an additional $5,000.
