Saw this on FB.... guessing i don't need to add any further comment! "Just finished my custom rear valance had the idea for a long while and finally decided to get on with it, don’t look too bad"
Comments further down on that post suggest he built some blanking plates to cover the vents while driving so perhaps not so ill thought out?
He probably didn’t understand the intricacies of an aircooled engine, thought it looked good and then his error probably got pointed out to him and he re modified it. We all had to learn I suppose!
