at umi they got 3 kinds... one thats poly poly and stronger then stock looking but non adj. for 69$, and then two adjustable ones at like 129$ ECT. first off what does it do.. i know it helps center the rear on lowered cars, a search told me that much, but what does it do for a guy whos not lowered, who is adding hp, and wants to add suspension to get his car to 60ft? is there any purpose.. i know the stronger bar with better bushings cant hurt anything! but should i spend the extra money for the adj. one.
