The Z isnt a race car thats for damn sure, and the originally posted wheels are a bit to F1 Size comparrison) to really be functional unless in a tubbed fender (your sig)/ open wheel race car.

And the original rims are something that I would see on a mid 80's japanese coupe with 6' over fenders and rocking the oil-cooler outside the front bumper. I just really dont like that style. I know its based off race cars of the era, but some of the cars ive seen that imitate it for the street are just silly.
