RENNtech Engineering GmbH now open

Wednesday, August 7th, 2013

RENNtech is pleased to announce the opening of our European research and development center in Germany. Located just outside of the famed Nürburgring race track in Mendig, Germany; RENNtech Engineering GmbH will serve as a development and testing center for new products and allow greater expansion into European markets through a wider product range specific to European only models such as A and B class in addition to the entire Mercedes product line. As a direct arm, RENNtech Engineering GmbH also grants access to new models months before they are released overseas allowing us to bring products for new models to market quicker.

As a further testament to our quality standards, our European branch will obtain TÜV certification for our street legal product line. Our latest M157 biturbo upgrade for the new 63 series as well as our 200 cell sport cat downpipes have already achieved TÜV certification with many more certified products on the way.

What is TÜV certification and why is it important? Basically, German registered road vehicle may not operate on public roads with modifications that do not meet strict quality standards put in place by TÜV. Testing of material construction, temperature and corrosion resistance, emissions and material analysis are just a few tests products must undergo to obtain this certification. All this ensures when you purchase a RENNtech upgrade you get exactly what we say; performance without compromise.

RENNtech Engineering GmbH is located at:

Robert-Bosch-Str. 30

56743 Mendig

Tesla S vs RENNtech tune only E63

Wednesday, February 6th, 2013


Published: Feb 05, 2013

The same Tesla Model S that successfully beat a Dodge Viper in a quarter-mile showdown is back this week going up against a Mercedes E63 AMG.

Instant torque is a wonderful thing yet EVs in general are not popular amongst gearheads and probably never will be. That doesn’t distract from the fact the new Tesla Model S is quite the performance machine. For last week’s installment of Drag Race Tuesdays we saw the Model S successfully beat the Dodge Viper SRT10 on a quarter mile strip. As a result, it set a new record as the world’s fastest production EV.
Now that same Model S is back, this time going up against a RENNtech-tuned Mercedes-Benz E63 AMG. So can the mighty EV repeat its incredible performance from last week? Check out this week’s quarter-mile showdown to find out.

Two new adjustable suspension kits for the CLS and E (C218 / W 212) available now!

Monday, January 14th, 2013

The RENNtech adjustable suspension spring kit lowers your vehicle with the OEM dampers via adjustable spring perches and sport lowering springs on the front and adjustable lowering links in the rear for the air suspension. This kit also works with vehicles that have electronically control dampers installed. Our lowering solution offers not only overall improved aesthetics and an aggressive vehicle stance, but improves both vehicle handling and performance.

 Our standard kit includes:

  • RENNtech sport lowering springs for front axle
  • RENNtech height adjustable spring perches for front axle
  • RENNtech adjustable links for rear axle

In addition, we also offer our adjustable suspension kit with the RENNtech Digital Suspension Lowering Module (DLM) in place of the rear adjustable links.

This setup allows the suspension system to remain balanced as the digital lowering module controls inputs to all four sensors on the vehicle (even though only the rear suspension is adjustable electronically). It also allows for complete adjustablility of rear ride height via the lowering module software (included) with no need to manually adjust links on the rear.

We feel that this combination best maintains the suspension system’s functional integrity as it accounts for the suspensions load leveling function, offers improved ride quality over the standard suspension kit with adjustable rear links and allows for complete electronic adjustability of rear vehicle ride height via the included software.

Kit Specifications:

  • Lowering Range: 20-40mm Front / 10-20mm rear with standard links
  • Four corner height adjustability of the original suspension kit
  • OEM electronic damper control is retained
  • Aggressive, lowered vehicle stance
  • Improved vehicle handling and performance

Upgraded DLM kit specifications feature above plus:

  • Lowering Range: 20-40mm Front / 45 mm rear with digital lowering module
  • Easy control of rear ride height with greater adjustment range
  • Front suspension level is accounted and adjusted for lowered ride height
  • Rear ride height can be adjusted on the fly via DLM software

Kit start at $1050.00
