Use your dial caliper to measure the wire diameter of the coilovers front and rear. Then call Aldan and tell them what springs are on the car and what the car is. They can tell you if you have the right springs on the car. If not, they will either trade springs with you or sell you the proper ones. I had Aldans on the last car I built. They are the Cadillacs of coilovers. http://www.aldaneagle.com/
