GMG Racing

Founded in 2001, GMG has quickly established itself as North America’s premier performance tuning facility and producer of racing components.


GMG produces some of the highest quality best fitting products for Porsche, Audi and beyond.  From roll bars, harness mounts and other safety equipment to exhausts and suspensions components.   Everything you need to get your vehicle track day ready, or just feeling tighter and sounding better on the street!      Their roll bars are made from 4130 Chromoly tuning to not only minimize added weight, but also to increase chassis rigidity.  Each bar is precisely TIG-welded and normalized right here in Southern California.


GMG is located directly across from Porsche Motorsport North America (PMNA). This close proximity has allowed GMG to build a strong relationship with the legendary racing brand and that has helped them support their customers to the highest level possible. From Club Racing to Sebring and Daytona, GMG can take you as far as you want to go.
