GMG is the West Coast's premier performance tuning, service and motorsport facility located in Orange County, CA. Offering leading independent service in Southern California for all Porsche vehicles - both newer water-cooled and older air-cooled cars - GMG features a state of the art 30,000 sq. ft. facility and 4wd chassis dynamometer, the latest factory diagnostic equipment, cutting edge laser alignment equipment, and factory trained technicians. We are not only a performance tuning and race shop, but we are also a complete dealership alternative that can perform all factory service, maintenance, and repair work.

Our factory trained technicians and Service Manager are all passionate enthusiasts with years of experience at Porsche dealerships. In addition, our diverse and extensive experience with both street and professional race cars gives us a far more advanced understanding of drivetrain, engine management, and chassis function than most repair shops including the dealership. This competitive edge allows us to think outside of the box and be able to quickly diagnose and resolve any issue. GMG works very closely with the local dealerships and also with all third party warranty and insurance companies. What separates GMG from other shops is our passion for the Porsche brand and our attention to detail, offering you the best service available anywhere. If you have a modified car and the dealership will not service it anymore, GMG is your place to have your car serviced. In fact, many Porsche dealerships throughout Southern California refer their customers with modified cars to GMG for maintenance, service, diagnostics, repairs, and performance upgrades.

We perform all factory maintenance and repair services including simple PPI's (pre-purchase inspections), track inspections, oil changes, fluid changes, brake servicing, diagnostics, suspension repair, alignment, complete engine and transmission rebuilds, and many more. To ensure that we maintain all aspects of your manufacturer's warranty, we use the latest state of the art diagnostic equipment and factory parts. Rare and high performance Porsche models such as the Turbo, GT2, GT3, Carrera GT, 959 are our speciality here at GMG. We also specializes in older air cooled Porsche models such as the 993, 964, and 930 models.
