    Default Pierce Car HELP!!!

    Have a 2007 Pierce, clamped up- running the coil-over eliminator on the front, , z-link right side, advanced oil shocks straight from pierce, straight bar- 2nd hole from top on rearend, all other bars are in middle holes. 50 lbs of left rear, and both rear shocks have the right angle in them.

    No matter what I do I cannot get the car to calm down, rough track or smooth track the left front is a foot off the ground and its very undriveable. I need to help calming it down. Any help is greatly appreciated.

    We ran our 08 with a 100 pound split in the front and it would carry the left front maybe a inch.

    How much drop do you have in the LR when you jack it up under the drivers legs? Should be between 4-5in, if you are closer to 5 i would close it up and see what you think. Is the car fast carrying the LF?

    It should be in the 120 to 140 pds heavier on the LF for the clamped up cars,25 pounds bolted on the LF will help it early in the night.30 to 50 pounds of LR works for most on ump tires.

    where is the spring on the RR? Looks like you may need to raise the panhard bar straight up on both sides. Or maybe a j-bar or long bar suits that hammer down track better.
