GLA 45, CLA 45 and A 45 Class Stage 2 Tuning Development

December 17th, 2014

RENNtech is pleased to announce that after  long term testing  our stage 2 performance upgrades are ready for the M133 engine.  Making 455 HP and 555 NM our stage 2 kit is the ultimate upgrade for Mercedes newest two liter turbocharged rocket.

 Since August, RENNtech and RENNtech Engineering in Germany have been pushing the tuning envelope and have made significant gains in performance including turbo upgrades and the ability to remap the ECU. Months of real world Autobahn testing of our M133 stage 2 kit has resulted in full TUV Certification.

 In addition to our stage 2 upgrade we currently offer a performance downpipe featuring a high flow, specially coated 200 cell catalytic converter. This converts exhaust gases better than anything on the market and unlike other downpipes will not set a check engine light during long term, high speed driving, even on US spec cars.

Future developments for the M133 include additional exhaust components and a unique carbon turbo heat shield. Our heat shield is crafted from the latest CMC carbon material which exhibits extremely low density, excellent thermal insulating properties and low thermal conductivity. This is a real upgrade and insulates the turbo charger rather than a stainless shield or similar material that actually conducts heat into the engine compartment.

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.
