Looking at my new 200s wheels it seems the lugs they sent are wrong. The wheel description says they require a 90 degree conical lug which I have. But looking at the wheel it has a countersunk area around the hole that looks like it needs a washer. And when I bolt them on the car, it seems the lug goes in pretty deep. Am I just paranoid?
The set that was on an off topic car I bought had washers on them. When I took the wheels off, there was an indent/recess that the washers set in, so I'd think if your wheels have the indent/recess I'd run washers.
i think the new ones look that way but just take an acorn. Although i wouldnt doubt they 'would' take some odd lug nuts. the old 200S's and i have many were and still are a pain in the *** getting lug nuts for. the last set i bought i had to turn down in a lathe.
Looks like an acorn seat to me. If they took a washer they would take a mag shank lug nut and the seat in the wheel would be flat not conical.
