It all depends on what you use the car for, if you are looking for a great launch on some slicks or drag radials a good set of adjustable uppers would be best. I have the frpp uppers and with my horsepower now I wish I had gone with some heim end adjustable ones. Like alot of things I will end up doing it twice. I am looking for some mega bite juniors now for my lowers cause I need more traction at the track.
