My daughter's boyfriend lowered (and ground effected) his 94 Cavalier. Without the ground effects it would probably be okay. Do you have front and rear swaybars? This would be a cheaper alternative to lowered springs. You should also be able to get regular springs in a higher rating ..or the same rating in a more "progressive" coil (varied spacing-light for the first xx inches of travel ..stiff for the remaining x inches of travel). The main problem that I would see is that any lowered spring (as in packaged) tends to be real low ..doing nasties to the steering/wheel/tire stuff. There appears to be a lack of definitive sources for your Corolla for swaybars. Plenty for the former generation and for the newest.
