I like mine, a while back someone said that they had a Hellwig bar that didn't fit good. Mine fit great. Was an easy installation.
One of my reasons for going with the Hellwig is that there is no wheel rub. I know some of you F-Body bar guys say yours wheel don't rub, but every Impala I've seen with a F-body bar rubs, also every car I've seen with the HA rubs and about half of the stock bars rub including mine. My Hellwig doesn't.
Once I get it on the track I may decide I don't like it and try the F-body bar, but right now on the street I like it.
