Paul already mentioned this, but I think it bears repeating... Does your 88 want to change lanes when you get on or off the gas? It could be because your knuckles are worn.
An added bonus of having this kit (other than the improved geometry) is that if the hole in the knuckle where the "long bolt" goes through is worn, allowing the links to change position. This kit eliminates that hole as the pivot point for the lateral and toe links. (Trailing link, as well.) Saves you the hassle of repairing or replacing your worn knuckles.

Are these only needed for cars that are lowered 1.5 inches or more?
The kit is designed to restore the rear geometry back to stock when you lower the rear 1 1/2". However, if you install it on a non-lowered car (or one lowered less than 1 1/2"), it will still raise the roll center, reduce the tendency to roll, and increase the negative camber gain in compression, so there is still benefit on stock ride height Fieros.
Fieroguru, I have one of these that I bought from you. I was curious why GM never did this in the first place. Any ideas?
Thanks for the purchase and support!
GM designed the 88 Fiero around the use of 14" and 15" wheels and this mod requires 17" wheels, so the simple answer is it didn't fit. It is pretty common for suspension and brake designs to be limited by the base model wheels used for that year.
