STG Racing Motorsports



Welcome to STG Racing, a division of Spartan Training Group, LLC and STG Firearms.

STG Racing is a motorsports performance parts and accessory retailer. We sell everything from brake pads and exhaust systems to custom one off fabricated performance parts for racing or street applications. STG Racing also works closely with a few select custom tuning and fabrication shops in Phoenix so once you‘ve made your purchase we can direct you to a trusted and experienced tuning shop. We only sell what we have used or are currently using in our own vehicles or road race cars on the track. Our website is new so check back soon to order online! In the meantime give us a call if you have questions or are ready to order.

Thanks for visiting STG Racing!
