Dont do it if your not serious! If you go autocrossing, and go half as quick as the rest, do you really want the same old "well its just a Pinto" from the other racers. Tires, wheels, big front sway bar, and shocks are what you need. And yes you have to compress the shock to adjust them, but then you have to extend them. Remember the two nails in my post!!! By the way, a rear bar is not worth the time as it hooks onto the floor boards, whick flex and soon or later will crack. AND LOWER THAT SUCKER!!!!! Been there/done that.
