I bought some Vortex side skirts from E38 show a couple of weeks ago for £80, got them sprayed for £90 and fitted them this weekend. Fitting them is quite easy but you could do with an extra person to help you with it, i did them myself and used Sikaflex to glue them onto the car with. The quality of the fitment was pretty much spot on, really good snug fit for aftermarket sills. Love how they look as well, they don't look out of place or anything, they look as if they are meant to be on the car as standard, they sit out quite alot in the middle so you always catch your leg on it when getting out of the car. Here are some pics, they match the S-Line front bumper a treat with the outer lips on the bumper.
