I have a set of lift springs I have decided not to use. I installed them and drove about 100 miles on them before I decided I would rather lower the whole car. Bought them off of JC Whitney catalog. I believe they are made by Dayton, but can't find the order form or part number. After installation, the back end lifted about 1.5" measured at the wheel well to the ground. $70 + shipping from 75070. Pic of car with springs installed and next to a stock spring .
