2011 OPTIMA Ultimate Street Car Invitational Preview- RENNtech C74 Konzept

The 2011 OPTIMA Ultimate Street Car Invitational, presented by KN Filters and Wilwood Brakes, is just over a month away and over the next several weeks, we're going to profile several of the competitors in this year's event. We're starting today, with the RENNtech C74 Konzept.

As the world's foremost Mercedes-Benz/AMG tuner, RENNtech's latest project vehicle features performance modifications and exterior aerodynamic modifications 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-inch 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”.

The exterior has a full compliment of aerro products, including the following:

- Full Carbon Fiber Widebody kit (prototype shown)
