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.
