Jim,I've never had one of these on any car I've ever owned, so pardon the Dumb Question......
Can you really feel a difference with these installed?
I can only speak for myself when I say that the difference is negligible. I can't honestly say that I feel anything. BUT, it's a beautiful piece of jewelry.
If I could find a Whiteline Rear Sway Bar on planet Earth, I'm sure that would have results that could be felt, but alas, I don't think the strut bar does much of anything except dress up the interior and look nice.
I don't regret getting it though. I like it A LOT!
