leaf springs

On 70 Barracuda with front and rear AAR sway bars, when I added SS springs at the next autocross race the rear end came around big time. The traction issues where gone, but had to remove the rear sway bar. I also got the biggest front bar that I could get which balanced with the rear springs. I have the SS springs in a 65 Coronet also with a big front bar, but have not driven yet. No shop will replace just one spring, always as pairs, even for rebuilding.
