Wheel data

[StarPD]

I've tried the "Search" function, and can't find what I'm looking for. Can anyone furnish a link to a folder or thread that provides detailed data on OEM wheels (18") for 2005 Q45? I'm looking specifically for hub center hole diameter, wheel offset, stud size and circle. Wheel weight would be great too, if available.

Also, do higher offset numbers indicate wheel center further out from the hub, or closer? I.E. wider installed track, or less?

If no such thread exists, does anyone have this info?

Thanks.
