Hey if you want to go cheap for $28.00 auto zone has these bolt sets that sqeeze your springs together. or you can inverse them and raise your car. I have them on my 92 celica st and I raised my car for the winter. They helped with the suspension. provided a more stable ride. DO NOT buy the rubber spacers they fall out and you may have a good chance of rolling out your car.
Ebay seems to have some check there.
be sure to get the adjustable kind. You may end up not liking the hight of the hit and see if that is what you want.
