New RENNtech SLS carbon fiber aero products now available!

June 13th, 2014









RENNtech set an objective to develop and create a state-of-the-art fully adjusting wing and rocker panels for the Mercedes-Benz SLS AMG. The result can be summed up in one simple phrase, functionality and quality without compromise.

RENNtech’s engineering and design teams spent countless hours perfecting the aerodynamic properties and aesthetic details. In order to properly develop such a superior product; RENNtech utilized 3D white light scanning, the latest in CAD surfacing technology, and rapid prototyping via industry leading Stratasys Fortus SLA machines.

The adjustable wing is comprised of a decklid lip spoiler that sits just aft of the factory retractable wing, which is now static. The lip spoiler features two highly integral stanchions which serve as both the connection to the upper wing element and the location of adjustable carbon fiber struts. Greatly improved downforce is provided predominantly by the centerpiece, wing element. The center section of the wing gradually pulls rearward and sharply terminates to further increase functionality. The latest in aerodynamic developments inspired extractor elements which are unmistakably unique styling features integrated within the 100% carbon fiber end plates. These extractors reduce drag by pulling air flow from the top surface of the wing, out through the sides of the end plates.

Our proprietary carbon fiber side skirts were designed to complement the RENNtech front splitter and rear diffuser. This side skirt kit includes 4 high quality pre-preg carbon fiber pieces; 2 rocker panel extensions and 2 rear fascia trim pieces. These exceptionally unique and refined aerodynamic pieces complete the RENNtech SLS aero package by integrating flawlessly with the original lines of the vehicle while boosting the overall testosterone level of the sporty SLS.

RENNtech SPEEDSHIFT Valve Body Upgrade w/ Throttle “Blip”

April 24th, 2014

The staple of advanced or professional driving is the “rev match”, or “throttle blip”, in which the driver quickly brings the engine up to speed with the wheels by use of the throttle. This was not possible with the automatic transmission in the CLK Black Series…until now.

RENNtech is proud to offer our Speedshift performance valve body upgrade for the CLK black series. Our upgrade modifies the shifting performance characteristics of the transmission control unit, the transmission valve body and allows the vehicle to automatically “blip” the accelerator upon down shifts allowing for quicker gear engagement and faster lap times.

When downshifting, the engine throttle is increased to allow the engine to match the RPM of the lower gear and allows for significantly faster gear engagement . When coupled with our transmission upgrade, this is the ultimate upgrade for your CLK Black series.
