Motorsport Enterprises Racing is known for the race-winning MX-5 Cup cars but can also build race cars for any race series. Take a look at the MER photo gallery to see cars we peeped for other series’ including the awesome GTR we built for the Silver Stat Challenge. Converting a street car into a race car is more than simply adding a safety cage. MER uses years of experience building race machines to consider every aspect of the car. Most importantly the car needs to be safe, but we always consider performance and driver comfort too. MER can assist in preparing your car for any level of competition. We build custom roll cages, install race seats, five point harnesses and other safety equipment. We also build fire suppression systems, install engine oil coolers, transmission coolers, differential coolers, custom brake ducting, flat bottom flooring, splitters, wings, diffusers, and more.
