Width and offset vary with the model:

M Double Spoke Type 369 Staggered
8.5X19 ET=38mm
9.5X19 ET = 48 mm

Star Spoke Type 368
8X18 ET = 43mm

Double Spoke Type 309
8.5X19 ET= 38mm

“Y” Spoke Type 308
8X18 ET=43mm

“V”spoke Type 307
8X18 ET=43mm
Thank you for the info! As long as the centerbore is atleast 72.5mm the wheel would work correct? (with the use of hubcentric rings)
Do you know where to locate the width and offset for the 28i 18" M sport wheels?

I'm looking at a 20" set of wheels that should mount up OK, however, they are offered in 8.5" and 9.5" widths w/ +35mm offset, so I'm trying to decide what option to go for (one width all around or staggered). I wouldn't mind the wheels moving further outward then the 28i M sport has from the factory, but I don't want to much offset where rubbing would be an issue
