This would make the Z/28 unsprung mass about 30lb lighter than a ZL1 in total, if one sprung for optional wheels vs standard. Unless my 77.9LB total is incorrect?

Actually, it's greater than that. First of all, GM's Curb rating is based on Base car, not "optioned" - up OR down. And, of course, MRC, for all is actual electro-mechanical marvels, is HEAVY...much heavier than the Multimatics, including wiring and controller (and NO, I don't have a
precise measure of that difference, but
someone may offer an idea). But the difference IN TOTAL (Base-to-Base) is nearly 40lb/corner...
