by KCPerformance Overview Projects

The wish of the client was a fast, sporty, and relatively small diesel sedan from Mercedes-Benz. This particular C-class sedan 350Cdi from the W204 series was a logical choice for this customer.The client had owned and driven several C-Class cars, so this was agreed to become something special. The car was imported from Germany for this customer to be entered in Belgium.The adjustments to the chassis were designed and performed by KCPerformance using Whiteline bushings that were specially developed.
The brakes were developed together with Hi-Spec. Also ATS Motorsport developed these 17" rims to fit on this Mercedes-Benz C350 CDI with the big Hig-Spec brakes. The original brake lines were replaced by steel woven brake lines from Goodridge. We also developed a strut brace for the W204 together with Wiechers. The top mounts needed to be replaced as these are underdeveloped. That is why KCPerformance develop better top mounts for the W204 in collaboration with Intrax. We removed the DPF filter and deleted it from the software. The EGR was closed via the software and we updated it to a KCPerformance stage 2 chiptune. This luxury Mercedes is now a fast gran tourer with all the updates. A real executive saloon for a young businessman.
