Not Ranked
Center bore to hub spigot size... Let me get my soap box. I've brought this up a few times and it's a real concern of mine. So many times I've seen people fit wheels without a correct center bore size and then have problems with broken wheel studs.
I think a lot of people don't realize that the wheel studs job is just to retain the wheel against the hub and transmit acceleration and braking loads. The hub spigot transmits all the suspension loads. If the center bore to spiggot doesn't match you need fit adapter rings to make up the difference.
With the Metric PCD there are ways around that. It's not difficult to re drill your hubs. Alternatively you can drill out the holes in the 4.75" PCD pattern in the wheels and use steel inserts to bring it back to 120mm PCD. There's not a lot of material to remove.
Cheers
