R Theory Motorsports

Since 2014, R Theory Motorsports has been working behind the scenes to design some of the latest and greatest aftermarket race parts. R Theory combines the best minds of the Engineering and Manufacturing industries to bring you quality parts that will stand up to the most demanding situations. “Engineered to Perform.” It’s not just a slogan, it’s their guarantee.

R Theory Motorsports started off making designing quality parts for the NA/NB Miata platform, but have now branched off to cater to many other platforms. Before releasing a prototype, careful measurement and consideration to material choices are made. Even more care and attention to detail is made before beginning production of any part they produce.
