You can get moulded mud flaps from Demon Tweeks, but I don't think for the Evo VII. Thing is, you have to drill the bodywork on the side of the car behind each wheel to fit them (ouch). What's wrong with the flat ones, as commonly used?
They make the moulded flaps that are use by the works teams. A mate of mine has some on his Grp N Escort Cosworth and they are the dogs wotsits. About 130 quid for the Cossy set, but not sure if they do them yet for the VII, lots of colours too.
