rear wheel arch
it has been proven that big gap within front wheel arch can produce alot of drag.
what about the rear arch , is it worth modyfying that ;
I am planning on securing properly foam on the underside of the front arch.
70mm thickness all the way around;
The rear arch there is huge voids in there. 200mm gap within the arch at the top of the rear wheels.
Is alot of drag created on the rears?
I have lowered the car but I don;t want it looking boy racer-ish therefore prefer to fill the underside of the arches.
