I have Moog springs in front but can't remember the part #. Height in front is about 26.5 inches with 215/60/15 tires. Tires in rear are 275/60/15 and the rear is about 27 inches high (measured from floor to wheel lip). I would like to go with 235/60/15 up front but I think this may put the front higher than the rear. Can someone recommend rear springs that increase the height to about 28-29 inches? I have Kirban variable rate springs on it now in the rear and they seem a bit low. Thanks.
