Sorry but the answer is no to the springs. the rear shocks are almost the same but the springs are a different diameter and won't fit without modifying the upper spring perch. (and would be way too stiff anyway) I had to have custom bits made to allow the bilsteins to use the lowered cressida springs on the rear. The fronts are totally different! at approx. $120 per pair for new springs, new ones for the car will be cheaper in the long run.
If you want to kill the bum up stance these things have, look for a post from TRD_Chaser, I think he used MX73 springs on the rear and MX83 on the front
