I have a similar color Z with same style wheels but with a red stripe around the rim.I found photos of Black 15" x 7" Advanti Storm S1 on a red Miata and IMO the wheels look great. of course they'd look much better on a MR2.
here is a video of a dud installing them on his car. again, not a spyder. so the wheels looks great, teh car is a mess.
