Do the job right. www.jagsthatrun.com has lowered coils at a reasonable price. I never did like cutting coils, and heating coils is a time consuming process where you have to remove the fenders and grille and pull everything away just to get at the springs. Heat or cool them wrong and one side is lower than the other. Save yourself a lot of grief, save your money and be patient. Buy the springs from a reputable dealer.
