"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. Thanks 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!"
