Those wheels were never sought after like the 4 lug pony wheels.
The 4 lug pony wheels were nostalgic for many years. I remember a 91 GT I had didn't have ponies, it had aftermarkets....I $hit canned those for some 4 lug pony wheels when I got the car done.
I had them on the rear of my car for a while... not that nice of an upgrade from fox ponys IMO. I would look for 17s and try and sell off the 4 lug ponys to help the cost.
I contemplated getting waffle stars to keep my tires when I do my 5 lug, but by then I'll need a new set of tires; and when I get a new set I don’t want to spend money on 16" tires.
