My cars going in for some work in the future, and I thought about a wing like that. I normally hate wings on notches, but I saw that pic a while back and drooled. I'd put one on mine in a heartbeat.
I'm not a huge fan of spoilers on notches either, but I was looking for way to get a third brake light back on my coupe. The whole rear was taken out and a bulkhead was installed.
Problem is the ASC spoiler is $$$ becuase it was only made for that limited run of foxbodies.
See that red car looks ok, but the only reason i like the autocross style wing is that the wing part is actually connected to the body....i can't stand any wing that sits up off the trunk even if it's only 1/4 inch...just looks wrong to me (on a coupe that is).
