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. 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. 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. 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. 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.
