Hi Steve
Is there any room for/chance of putting a Intercooler or charge cooler in the front wing, between the wheelarch liner (if it has one) and the bumper? Many OE installations use this for IC location, the possibility of using a charge cooler overcomes the problem of limited air flow in that area and lets face it, the space isn't much use for anything else! :lol:
Just a suggestion.
