Getting ready to rebuild the front end,bought a full kit from Performance Suspension Components but now looking for front springs. I'm an old SCCA club racer so I thought i'd try to make the old stove bolt handle well to. Any one have any insite on some good performance springs? I plan on using Koni adjustable shocks and would like a good progresive rate with about 1 inch to 1 1/2 inch drop.
