FWIW, I don't have a bumpsteer kit, and I'm lowered 2" on
Eibach Sportlines but I do have MM c/c plates. Only thing I needed to do to give it a better ride was to get fox body struts up front because with the 2" drop, the travel on the struts was pretty much bottomed out and when I would hit a large bump, it would make a huge thud noise and it sounded like the car was going to explode. I ended up going with KYB GR-2's which aren't adjustable but they were pretty inexpensive and get the job done for the time being. They required a little modification to go in, but it wasn't more than a bit of grinding and 2 spacers made for each side.
As for springs, I got my Sportlines used with 2k on them for $100, and thats why I bought them. If I was going to throw down the cash for new ones, I'd get the H&R Super Sports. The Sportlines sag ever so slightly in the back, but other than that they are a great spring. The handling is MUCH improved over stock. Just my .02.
