Scary ride
 

Tuesday, a nice warm day in Wisconsin, (65°F) and I had the urge to take the stang out for one good ride. From a roll (5mph) took it to about 5200 RPM and when I hit 2nd gear the car went wild, and leapt to the left lane, (driver side) scared the #@$% out of me. I have adjustable lowers, and need to know which one to adjust, and should I adjust it up, or down? need some help here. What should I do to straighten the beast out? Well, not much of a beast, at least not until procharger sends me some help.
ps. Tire pressure was fine all around, and all corners are within about 1/8" Just don't tell me my posi unit is shot.

Take it an alignment shop and let them do it. Ask for a thrust or a 4 wheel alignment.

I already did that, and the rear isn't adjustable for the alignment, only the front.

When you have adjustable control arms out back, your rear can now be adjusted for alignment. Try either adjusting the right control arm to be longer or the left to be shorter. To do it yourself, you need to go to the drag strip and some 60' runs to verify your adjustments are correct.
