I am considering lowering my car an inch. I looked at the WCF 1"/0.75" lowering spring kit and they recommend moving the bump stops. Is the general consensus that the stops should/need to be moved for a 1" lower?
I dropped mine an inch without lowering the stops, it bottomed out against the stops so hard it knocked the mirror of the windshield. Before I drove it again, I cut and lowered the stops. If you have a welder and cutoff wheel it's an easy job, took me about an hour per side.
Is the bump stop welded to the swingarm or is it bolted? I've had that problem with mine bottoming out also. I removed a round and a half from the springs.
I think it really depends on the spring rates of the lowering springs. I lowered my 85 with Eibachs which dropped it around an inch, I did not modify the bump stops and it seemed fine. On the other hand, my 87 had been lowered before I bought it with cut springs, I believe more than an inch, and it rides like a train car because the bump stops were not modified. I have been tossing around the idea of swapping my cut springs for the Eibachs I have in my garage but I love the stance it has now. I have also considered getting the bump stops modified, but I think I would bottom the nose out a lot more if the suspension had more travel.
Mine was an 84, and although it does require cutting and welding it only took about an hour a side to shorten them.
You must work with phenomenal speed... or you've done this a bunch of times and are well versed in all the steps required. Took me considerably longer than "an hour a side" when I took it all apart to do the job. But it was well worth it. My '84 handled a whole lot better at autocross when I actually had a lowered front suspension that was not just sitting on the bump stops any longer!

I was a heavy equipment mechanic for 30yrs, so to me it was a minor job. Most of the machines I used to work on the tires alone were heavier than the entire Fiero. Plus having over $50,000 worth of tools helps
