Went to the showroom to try on some race gear for sizing. The Sparco boots I wanted weren't in store but Garreth was more than happy for me to order two sizes and return the ones that didn't fit! Defo recommend

Fantastic Company and Service, GSM have kept me updated at every stage. The Sports Seats have now arrived top quality finishing, can’t wait to fit them. I belong to several Car Clubs including BMW Cornwall and will certainly be recommending GSM performance to my colleagues.

Such a good team and a really good well put together website.
Made ordering my new seats for my car such an ease. Glad I got recommended by a mate.
Will be telling anyone else who wants seats to check out these guys �
