Just some user input here. I had to remove my sub because I was getting my amp getting warranty work on it. Well, I had never put a strut bar in the back because the sub was always in the way. Well it happens that my friend sold his integra and sold me his rear strut bar super cheap. I installed it right away. I know strut bars make a difference but this was the most noticable difference in cornering I have felt since getting my falkens put on. Understeer was drastically reduced. So for those of you sick of your front wheel drive understeer, try a rear strut bar.
