After all these years, I just noticed in the 86 Daytona catalog says that 'vented' rims were a No Cost option on Zs. Vented rims are the 5-lug swiss cheese wheels (they are pictured). I've only known those to exist on 85 Lasers.
Anyone ever seen an actual documented 86 Daytona with Swiss Cheese wheels? NOT available on 85s by the way.
