Final push re vg's, i can't comment on any vehicle except the kamm back crx, i do know this why is the back glass rain free when without the vg's i needed to use the rear wipers which are now history....so technically i gained or better yet lost, lost a rear wiper and motor less drag and weight ask me if i am complaining for me the vg's work and i get a few k's to boot................results will vary if you are driving a semi or a cool v dub.......no grill blocking there but a skirt project if i ever saw one...........
