All the front parts, strut, spring, front sway bar are discontinued from GM
Rear bar is still available
Rear springs maybe available you need the RPO code for the FE2 to find it.
Rear strut discontinued.
Why are you not happy with the FE1 suspension? Is it too soft riding, or is there a handling issue you are not satisfied with? You bought a 13-yr old car (with unknown miles to us) that may need some strut/shock replacement and some other replacement bushings in the sway bars. We need a better definition of why you are not a happy camper with that car? Thanks
