"More downforce and faster lap times... I Just love this diffuser from Difflow! It looks sick and it draws comments at ever cars and coffee event." Tim, Irvine CA

"Just mounted my railer 5 element diffuser to my Exige cup car today. It looks great and the fit was perfect. The overall diffuser is much stiffer and more stable when mounted. Ran the diffuser at the track this weekend and really liked it. It seemed to improve high speed stability and made the car feel more hunkered down. It certainly drew a lot of comments."
Edward, Newark DE

"We did a total of 13 high speed runs over 200 MPH at the Texas Mile in our Nissan GT-R. The diffuser felt very solid. We were able to achieve the 2nd fastest top speed in the world at 217 MPH for a Nissan GT-R - thanks Difflow!"
Jeremey Rohrs, SouthSide Performance, Houston TX.

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?
