We have been dealing with the topic of refinement and tuning of automobiles since 1992. The focus for us is not on any particular car brand, we only want a perfect result for the customer, whether small car or luxury class. At that time, the Opel brand hit the bull’s eye with the Astra H GTC Coupe.

JMS refines the GTC with body parts individually developed for the vehicle. The kit consists of a Racelook front lip, side skirts and a breathtaking rear diffuser. At the rear diffuser there is space for a central sports exhaust from JMS, but any exhaust system fits at the rear (left, left / right, center). The tuning measure is rounded off with @hr special springs from our range and a @ozracingwheels set of rims.

We look forward to your visit to us on site (exhibition with around 90 premium aluminum rims) or in our webshop.
