R Theory Fender Vents for Mazda MX-5 NA NB

R Theory create some of the most well-engineered Mazda MX-5 race components in the world.

When travelling through the air, particularly at high speed, your tyres cause turbulent air which then builds up pressure within the fenders. This build-up of pressure causes excess lift and drag, potentially slowing down lap times and decreasing traction.

R Theory’s vents eliminate this by relieving pressure under the fender and have been specifically designed to only allow air to escape, and not force more air into the fender.


  • 2 x Aluminum Fender Vents
  • Installation rivets
  • Templates for cutting the fender
