So I got mine installed and got an awesome basemap from Steve so I've been test driving it around and im hearing the headers scrape against the sub frame. Little freaked out. I've heard I need to get a rear motor mount to fix this by hasport. Didn't realize they're are multiple ones. Do I get the street one or the race one? Keep in mind I just daily drive my car so I don't actually race it. So either the 62a or the 70a. Anybody have experience which would be better for daily driving?
