I put those ventshades on all my vehicles but they don't go on my ESC coupe for obvious reasons. I like them cause I can leave the window down about an inch and my cigar smoke will be drawn out. I'm thinking that's why Texas Jim might like them for those old ciggs. Yeah I've seen you on that Thursday night chat you're like me you like that burley ,remember I'm from Kentucky! LOL!!!
Once I got past the blasphemy of putting Ford parts on a GM car I believe this should work fine. Those are some large diameter coils. As far as the ride you know it will be much firmer,but that is part of what you are after. I think you are on the right track, keep us updated.
