ECU UPGRADE

Our proprietary ECU upgrade for Mercedes Benz offer huge gains in performance across the entire RPM range without sacrificing around town comfort or daily driver reliability.

EXHAUST SYSTEM

RENNtech stainless steel sport mufflers are hand made and rigorously tested to remove any unwanted resonances in the cabin to deliver a deep sound that keeps with the character of a luxury performance vehicle. Our mufflers offer incredible sound in a lighter than the stock weight exhaust with improved performance. This is accomplished by reducing exhaust system back pressure and improving exhaust gas flow.

LOWERING MODULE

The RENNtech V3 Digital Lowering Module (DLM) is designed to work with all available Mercedes Airmatic or ABC (Hydraulic) Suspensions.The unit allows the user to have full control over all four corners of the vehicle’s suspension and adjust in 1mm increments. The DLM requires no splicing or soldering to the factory wiring harness. The RENNtech harness utilizes the factory pins as to allow a completely reversible installation.

The unit also supports speed-dependant lowering that allows the vehicle to return to its factory ride-height at a pre-set speed. This removes the need for the vehicle to be aligned after lowering. The user can maintain the factory longevity and still have the lowered look at low speeds! All RENNtech DLMs are adjustable via USB using either Windows or Android OS.The software allows the user to adjust the ride-height at each corner in 1mm increments independently.The software also has three locations where the user can store pre-configured suspension setups for quick changes.

TURBO UPGRADE

More power isn’t the only performance benefit as our turbos spool quicker, offer a more responsive throttle and immediate power delivery thanks to a reduction in exhaust back pressure, rolling resistance, higher RPM's and a lighter rotating mass. In addition, our turbo upgrade kit includes new high quality lines and fittings wrapped in heat resistant sleeves with every detailed piece manufactured and tested in-house to ensure years of 100% trouble-free and leak proof operation. These lines are made specifically to adapt to our turbos as this isn’t just an OEM unit with machined internals; but a dramatically larger, more powerful turbocharger that blows away anything else on the market! The RENNtech performance turbo upgrade is truly the ultimate in performance.

FORGED WHEELS

Our signature design that personifies performance and luxury.

RENNtech and ADV.1 set out to develop the Deep Monolite wheel program with an objective to create a product that features the perfect blend of high performance specifications along with quality and durability that surpasses OEM standards. 

These are not your typical aftermarket wheels given that each set is designed and weight optimized specifically for each application.  Countless hours of testing and development were essential to produce the lightest, strongest, and highest quality wheels available for Mercedes-Benz and AMG vehicles.  Experience the assurance of unparalleled service, warranty, and reliability from RENNtech.

HEADERS

RENNTECH stainless steel and ceramic-coated exhaust headers offer true bolt-on installation, mounting directly to the OE down pipes - and all RENNTECH headers are hand built from mandrel-bent, seamless tubing and CNC machined stainless flanges. Advanced computer aided design (CAD) and flow-analysis software allows RENNTECH headers to deliver substantial gains across the entire RPM range.

CARBON FIBER AIRBOX

By optimizing the path and increasing the volume of incoming airflow, our carbon air box is able to offer great gains in addition to serving as an attractive under hood showpiece.

Our kit comes complete with high flow performance filter inserts and anodized aluminum MAF sensor retaining clips.

EXTERIOR CARBON FIBER

The carbon fiber visually enhances the rear of the CLS, acts as a functional component of the vehicles exterior in order to decrease drag and increases rear down force. This is accomplished by improving the underbody airflow and allowing for a smooth transition to ambient air when the vehicle is at speed.

DOWNPIPES

Our performance down pipes replace the restrictive stock exhaust with high flow, 200 cell sport catalytics for improved performance, reduced back pressure, greater exhaust gas volume and better sound.

INTERCOOLER UPGRADE

Our additional intercooler pump and separate auxiliary cooler upgrade dramatically improves the cooling ability and capacity of the stock intercooler system.

This increase in flow and capacity removes heat from the incoming air; allowing for a denser air/fuel mixture and substantially cooler charge air temperatures over the entire operating range. Our pump upgrade kit provides an additional pump with a separate high efficiency radiator and includes all necessary plumbing, electrical connectors, mounting hardware and installation instructions.
