What We Do


R Theory Motorsports started off making designing quality parts for the NA/NB Miata platform, but we 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 we produce.

We know that sometimes you might have an idea stuck in your head for your car, but you need help making that idea a reality. R Theory Motorsports is here to fill that gap. We can help design almost anything for any car. If you can imagine it, we can probably make it a reality. Send us an email for any inquiries for a Custom Design and a quote.
