"I was so pleased with the look of this diffuser. It changed the back end of my GT-R completely. The diffuser was in stock when I ordered and it arrived safely and well packaged. I was able to install it just in time for my track day. My lap times were actually 2 seconds quicker than my last track day and all i did was install the diffuser. Needless to say, the product really does work. Thank you Difflow!" Quin from Carmel, 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 from 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!"

Built for Function.
All of our diffusers have been put to the test on tracks all over the world, including the Texas Mile, Nurburgring and Laguna Seca. Our customers were very pleased to see higher top speeds and faster lap times thanks to the significant reduction in drag from the Difflow Diffuser. Looks are just a plus!

Aluminum Works Best.
There is no better material to make diffusers from than aluminum. It can be powdercoated any color. It won't crack on a speedbump or curb like carbon fiber does. Why spend all of that money on a fancy carbon fiber diffuser when 75% of it is hidden underneath the car anyway?

Quality Workmanship.
We are the only company out there that stricly specializes in diffusers. Our 25+ years of experience in aluminum and aerodynamic part fabrication puts us ahead of the competition. From start to finish, everything is made in the USA and built to perfection. We ship worldwide, give us a call today!
