Built for Function.

All of our diffusers have been put to the test on tracks all over the world, including the Texas Mile, FL2k Drag Strips, Nurburgring, Laguna Seca and more. Our customers were pleased to see faster lap times, better stability and improved downforce from the Difflow diffusers and products.

Genuine Materials.

Our rear diffusers are made out of aircraft grade aluminum to handle curb rash, track abuse and exhaust temperatures. Diffusers are powdercoated black to maximize longevity. Why pay thousands of dollars for a carbon fiber rear diffuser when 75% of it is hidden under the car anyway?
