2005 Lotus Elise "I got my Railer yesterday, it installed like the stock dif and had it on in about 10 mins. I have my Ohlin's set fairly soft due to the back roads that I run on. I can feel the car being sucked down at around 90 mph. I normally only go to 120+ on nice roads, but I thought I would try it and got up to 129 on a bouncey back road with complete confidence compared to without it." - Darrin, Piqua OH. 2010 Lotus Evora "So wrecking the car ended up being not too bad of a deal afterall. Glenn from Difflow offered fabricate a new one for me and look what he came up with!! I still have to replace the diffuser finisher, but wow it looks awesome! The build quality is top notch and the whole thing is very light. I don't have a good "before" pic for comparison, but this looks just right for the Evora! Maybe if I would have had this in the car prior to my accident the added downforce would have kept me on the pavement " - Todd, Wexford PA. 2006 Lotus Exige Cup 255 "Just mounted my railer 5 element diffuser to my 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." - Ed, Newark DE 2005 Lotus Elise "Around 80 MPH the car has tended to want to "shift" less, and feels slightly more grounded. The rear end seems less twitchy compared to just a front splitter/stock diffuser during this weekends canyon drive. So I highly recommend any diffuser upgrade if you have front aero done. The windnoise above speeds of 45mph have decreased significantly compared to stock diffuser/exhaust exit. The product looks very professionally made and came to me very well packaged. Much better than expected from a start-up company." - Joachim, Littleton CO. 2008 Lotus Elise "No track time yet but I didn't notice any additional understeer in the first few test drives on the local twisties. Hopefully I can decide on a splitter soon. Much thanks to Glenn in his excellent customer service!." - Mike, McComb MS. 2006 Lotus Exige "I got the diffuser Friday and got it installed in 15 minutes. Looks AWESOME. I am also running a large custom motorsports wing with some fabricated adjustable height stands. Based on some very preliminary runs, it looks like the wing is grabbing more of the clean air generated by this larger diffuser and it is actually beneficial now for me to take the wing height all the way down to it's lowest position. Greater downforce with less drag, and a wing closer to the body line of the car doesn't look too shabby either." - Steven, Placentia CA. 2006 Lotus Elise "Glenn, Thanks for the quick response. The car definitely feels more "solid" above 50 mph. SouthBay AutoHaus did the install, along with a VF II supercharger and VF muffler. It is now a completely different car, in a good way. You do nice work and your service matches, always refreshing." - John, Hawthorne CA. 2006 Lotus Exige "I was on my way home from the 13hr headlight brigade race at VIR last night when I took on a sleeping deer in the middle of the highway. My headlights are aimed low and I didn't have enough time to swerve. I thought for sure my front clam was going to be mangled, but thankfully it wasn't. It made one heck of a bang though! Check out the diffuser, sharp as a knife! Must have cut that deer like swiss cheese. I kind of wanted to go back to see if the deer was sliced into several pieces then wondered what the deer would have looked like if I had the 5 or 7 element." -Aaron, Summerfield NC. 2005 Lotus Elise "I finally got mine today, it took me 10 minutes to take off and 10 minutes to put the new one on (by myself) and without lifting the car. Perfect fit and amazing craftsmanship, better than the OEM!!!" - William, Miami FL. 2006 Lotus Exige "It finishes the aero package nicely: Railer + CF Exige Splitter + CF Canards + 1650 mm wing). The Railer weighed in 12.6 lbs versus 6.4 lbs for the stock diffuser. I've lowered my ride height by 10 mm, so the railer is 4.25" from the ground. It's still very driveable. I have a 3.5" lip where my driveway drops off to the city street; it takes care but I can clear easily without scraping." - Amber, Lake Jackson TX.
