On a recent trip to Thermal Club as a guest of the members, I experienced A whole new appreciation for the sport. After returning home, I purchased a GT3 that was built by GMG. The attention to detail to the build of the scar left me in total awh. Following the purchase, I followed up with a new McLaren 570 S along with a Ferrari 458. GMG James F. Sofronas of the 570 S McLaren which was absolutely amazing. GMG Racing Scott starting a build on the Ferrari 458 and looking forward to having tons more fun with the three of these cars. Highly recommend GMG if you are looking for the best of the best in the racing world!!

I worked with Allen regarding my 2004 996TT. He was excellent in explaining my options and making recommendations. The results of the work performed are great. It's all smiles when stepping on the gas peddle!

GMG just completed installation of of a roll bar and harnesses along with a couple of cosmetic tweaks and it all came out to perfection. The team at GMG obviously takes a lot of pride in the quality of their work and it shows in everything they do from track to street. Allen, Scott, Hector, and Rueben are just the best. Thank you gentlemen for another outstanding job.
