Top Speed in Alpharetta is not a typical car shop — it will customize cars to maximize their speed and racing ability. The shop mostly focuses on suspension, installs and builds, tuning, and track support. Top Speed has the ability to turn any car from Toyotas to Porsches into racing machines. It also sells various, precise car parts and has a blog where racing fanatics talk about all the racing action. Products are available to purchase at both the store and website.
