General Info

If you have ever owned a performance car then you know how difficult it can be to get good work done if your car has been modified. The dealerships won't touch it, the local mechanic thinks your car is cool but has no idea how to work on or tune it, and and even some performance shops just cannot be trusted. We understand that you want to have your car, your way, so that you can have fun driving and enjoying it the way you want to. SGC was started over 20 years ago to give domestic car enthusiasts all over the world a reliable place to go when they need their cars modified, tuned, and maintained. Our private shop is not your typical garage. It is equipped with a state of the art Dyno and tuning facilities, secure access and climate controlled storage facility, and a dedicated team of expert tuners and mechanics who do nothing but build, tune, and maintain domestic performance cars.
