Suspension set up

1st thing I would do is unhook the front sway bar, it keeps the front end from rising on launch. Get the front low as you can. On the rear, with just leaf springs, un clamp the rear segments and clamp all the front segments, you want a stiff front segment to keep the rear from rotating. A good adjustable shock on front and rear will go a long way to help in hooking it up. Rear shocks need to be as stiff as you can get them and still plant the rear tires and keep them there.
