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.
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
