Mercedes-Benz C63 AMG Receives Power Boost by Wimmer RS

When it comes to German tuners, the name of the game is power. The more the merrier. In its latest take on the Mercedes-Benz C63 AMG, Wimmer RS has presented the Level 3 performance kit, which increases the 6.3-liter V8 engine's output to 580-horsepower and 690 Nm (509 lb-ft), up from 457 HP and 600 Nm.

To bestow over 120 HP on top of the already potent naturally aspirated V8, Wimmer RS made a series of upgrades including the addition of a reprogrammed ECU, air filter from K&N, air induction optimization, a new sports catalyst and optimized cat-back all-stainless steel exhaust system.

The tuner also fiddled around with the the electronic speed limiter allowing the C63 AMG to reach a limited top speed of 305 km/h or 190 mph.

As an option, Wimmer RS offers a KW-Club Sport Suspension and high performance Dunlop Sport Maxx GT tires.

The cost of the full performance level 3 kit is set at €9,900 (about US$13,800 at today's rates) including installation.

Wimmer RS Turns VW Golf R into 478HP Red Devil

Red Devil is the name German tuning firm 'Wimmer RS' chose for its latest take on the Volkswagen Golf R. 'Red' because of the color chosen for the car, and 'Devil' because this Golf R packs a sinister punch under the hood...

In stock form, the all-wheel drive Golf R rolls out of VW's factory with a 2.0-liter TFSI producing 270-hp and 350Nm / 258 lbs-ft of maximum torque. After Wimmer RS's engineers perform their magic, those numbers increase to a whopping 478-hp and 610Nm or 450 lbs-ft.

The extra power comes from a variety of mods including -but not limited to- changes to the turbocharger, ECU, air intake, injection nozzles and exhaust system.

According to the tuning house, the upgraded Golf R can reach an electronically limited top speed of 291 km/h or 181 mph.

Additional performance enhancements include a coil-over suspension set and more potent braking system.

The German tuner did not release info on pricing.

Wimmer RS and Dunlop team up to create a 190-mph Mercedes C63 AMG Racer

Wimmer RS has turned its attention to the Mercedes-Benz C63 AMG to create the Dunlop Performance show car. The performance is there, so don't worry about the looks for now; this is just a rolling ad. What's under the vinyl and stickers is what Wimmer can do for the C63.

The car's electronically-limited speed has been elevated to 308 km/h (190 mph) thanks to reprogramming the ECU; with the addition of a flurry of intake and exhaust mods, the car puts down 540-horsepower (+53 hp over stock hi-po V8). Torque figures have not been released.

The speedometer hits the 100km/h (62mph) mark after 4.4 seconds (traction control issues, perhaps?) and then the next 100km/h goes by in another 8.2 seconds (0-200km/h or 124mph: 12.6 sec). Keeping the car planted on the ground is a KW3 coilover setup hidden behind 19-inch rims and possibly unmodified brakes (Wimmer didn't mention anything in the press release).

Now, for the real shocker: the 19s are wrapped in...drum roll please...Dunlop Sportmaxx GT tires (sized 235/35-19 in front and 265/35-19 in back).

According to Wimmer, the car seen here took place at the 2010 Tuner's Grand Prix at the Hockenheimring in Germany where it won runner-up. Nifty.
