if this is the same thing as the jim fab bar ive heard its really good... a couple friends of mine have the jim fab and they have had no problems with it messing up alignment.... you do have to realign the car after install but once you do that you're set... the hardest part is tuning the bar the way it works best.... its a pain in the ass but it greatly increases straight line traction and launching and the people i know with it have seen drastic improvements in their 60' times which usually equates to better 1/8 and 1/4 mile times.....
