The only drop spindles available for the 88 are what used to be Held/Ryane or whoever the heck they are this year.
There were some serious questions regarding the quality of the most recent pieces. (One person had one to come apart.)
Jeremy from TFF/Fiero Factory was/is supposed to be in the process of acquiring the product line. If he does, I have every expectation that the quality will be top shelf.
I have no idea where that stands, however.
In spite of all the "nay-sayers" I cut the springs on both of my cars. (A spring has no idea how long it is, or how long it used to be, as long as it's done correctly.)
One coil is usually plenty, to drop the front level with the rear.
My gray car is running 86 GT springs on the front, cut by 1.25(?) coils. Theoretically, it results in a bit higher spring rate than the 88 springs. It rides fine, even with poly bushings.
