RENNtech C74 Konzept based on the Mercedes C63 AMG

RENNtech C74 Konzept based on the Mercedes C63 AMG provides wide body kit totally made from carbon fiber, rear deck lid spoiler and front spoiler also made from carbon fiber, a rear fiber diffuser with some integrated exhaust tips and some wheels made from aluminum that measure 19 x 9.5 inches for the front and 20 x 10.5 inches for the back. Those wheels are wearing some Nitto INVO Performance tires that measure 305 / 25 / CR 20 for the rear and 275 / 30 / CR 19 for the front.

When we talk about the performance provided by the RENNtech C74 Konzept we can remind here the air filters, the custom air inlet panel, the throttle bodies of 88 millimeters and the polished cylinder heads and the modified ported. The car also has some ECU and TCU software upgraded, a braking package made by RENNtech and a performance pipe.

RENNtech C74 Konzept

As the worlds foremost Mercedes-Benz/AMG tuner, RENNtech unveiled their latest project vehicle at the 2010 Festival's of Speed in Orlando, Florida. All performance modifications and exterior aerodynamic modifications were designed, developed, and tested in house at RENNtech's facility located in Lake Park, Florida.

The C74 is the latest variation of RENNtech's C63 AMG project vehicle which has seen continual transformations throughout its life, serving as a working test platform for RENNtech's proprietary line of performance products. The C74's current trim boasts incredible performance from the 6.2L AMG V-8 with a wide stance and aggressive look to match. The "74" designation given by RENNtech, refers to the 74 inch width of the rear wheel track which lies beneath the body work of the C74's muscular rear end. This allows the ability to run up to an 11" wide rear wheel with a 315 series rear tire for the ultimate in handling and traction. The number also pays homage to the legendary RENNtech V12 "SL 74".

This package is available now starting at $11,950. For more information regarding our C74 package and additional pricing options, visit our news blog: http://news.renntechmercedes.com/
