The 184 hp SLK200, which is the base model, received from the tuner a boost up to 210 hp and 310 Nm of torque, enough for a top speed of 242 km/h.
After that comes the 205 hp SLK250 which gets a bump to 244 hp and 360Nm with top speed of 250 km/h. And finally the V6-powered SLK350 which gets 330 hp and 390Nm of torque for a top speed of 269 km/h.
As for the appearence, the new tinted 20-inch wheels and the lowered suspension most certainly add some drama and style to the car. In addition, a carbon front spoiler, a bootlid spoiler and a rear diffuse have also been installed.
Finally, AMG-style tailpipes, upgraded rakes with bigger discs and calipers, aluminum sport pedals, VATH floor mats, and a new instrument cluster with either 300 or 330 km/h speedo are the other parts of the package VATH created.
Sounds good, looks better, so it really seems to me the guys at VATH did a really good job!
