A guy at the track had me level the 12l4 side to side at the back of the chassis. I used the tweak screws to do this. The car was almost undriveable the next heat. Re checked the tweak and it was way off. Set the tweak back to neutral and then the car handled like it old self. Is there another way to set the side to side ride height? I am sure the battery is making the one side ride low.
Thanks for the tip about the offset axle height adjusters. Gives you 1/16" more room for a bigger pinion.
