[TahoeM3]

I ordered it on my M4 but my dealer messed up and left it off. I have it on my e93 M3 and the difference is very subtle. I think it's a worthwhile addition at the price, but don't expect a night and day difference. It's just not there on normal roads. Maybe if the roads were really bad it might be more noticeable...not many pot holes or frost heaves around here.
