The tuning firm Piecha Design has released a new program for the Mercedes ML called the Evorian RS. This kit also fits the GL-class X164, and consists of a front spoiler with integrated LED daytime running lights, new side skirts, chrome aerowings, and a rear diffuser. Exhaust sound and performance was improved with a Quadro-4-tube exhaust system and dual chrome plated exhaust tips. For the wheels and suspension on the Mercedes ML, Piecha hooked it up with new rims and tires, and a H&R coilover suspension kit to lower the ride height 35 mm in the front, and 50 mm at the rear. Performance tuning features a Power Converter Intermedia RC, to improve the acceleration and response time of the Mercedes ML pedal at low speeds.
