I have 20" wheels,eibach pro kit springs,and eibach shocks.I had the stock rear sway bar and I replaced it wih the BMR one.Now the car feels really stiff in turns,handels awesome,BUT the rear now seems to be siveling slightly when I'm doing like 90-100.Is that because it got stiffer and since it's lowered one of the sides went out some and needs to be bourght back in!Am I on the right track?If so how do I adjust the panhard bar.Does it have to be adjusted to shorter than the stock?How will I know I have it adjusted to the right lenght!
