Collection: String Theory Garage
String Theory Garage was born out of a dedication to making cars drive better than ever. Founded in 2018 our passion, enthusiasm and knowledge of vehicle dynamics, suspension tuning and chassis setup has already built us a reputation for going above-and-beyond to supply and fit the right parts for your car. Every car that enters our garage is treated as our own, and does not leave until we, and you, are happy.
Here at String Theory Garage we stock a large and ever expanding range of Parts. A complete range of upgrades, all tested, developed and proven on our own car's. From Suspension upgrades to ECU tuning we have you covered.
We also offer full fitting with ride-height, corner balancing, and geometry setup as well as other services from our garage in Stratford upon Avon.
