My springs are very much original too.I ran the H&R Super Sports with Tokico Illumina struts and shocks on my 93 Coupe and it was a really good ride and performed on the curves really well. The springs are supposed to lower the front 1.5” and the rear 1” but mine didn’t drop that much. I attribute that to the springs that I removed were stock and were used and I installed urethane top and bottom isolators on the front and bottom on the rear. I think the drop was more like 1” and 3/4” but again the old springs were worn.
Honestly the reviews for the H&R springs and old posts talking about them all praise them for how good they ride and preform. The only reason I was second guessing them is because of the 1.6" drop (as listed on LMR's website). It feels like a lot.
But another good point about the isolators... I am replacing them too and my engine does have aluminum heads and intake which will help with the weight some too and also help with the drop.
