Are coil-overs the only option for the rear? Im not really familiar with the independent rear suspensions quite yet.

You can change the "stack" of the shims that mount the spring to the rear axle cover. I don't recall the "stack" in the ZR-1 but there's 6.1mm, 5.2mm, 4.3mm and 1.72 available. They're done in combinations on some applications. Maybe yours has already been done that way. A couple/few less mm on the top of the spring could effect it maybe more than one thinks. Measure what is there.
On the spring bolts at each end of your spring are there castellated nuts that are cotter keyed? If they're cotter keyed and 192mm long they're original to the '90, if they're 225mm they're later ones and if there's no cotter keyed nuts then they're after-market. Changing the stack and using the longer later bolts with cotter keyed nuts would maintain the "stock" appearance or just use still longer bolts but use castellated nuts and cotter keys.
