We have seen Piecha Design tuning German machines in the past but now we see their latest attack on the Mercedes-AMG W205 C63. Cosmetically the revised body kit adds some anger to the car without ruining the original design and those massive 20-ince Piecha MP1 Monoblock rims complete the looks rather nicely. Performance has been bumped up from 469hp to a whopping 603hp capable of hitting 100km/h from standstill in just 3.8 seconds. That is a full 0.3 second improvement on stock which is a hell of a lot. Not the biggest wagon / estate fan but this must be quite thrilling to drive.
