Another wheel offset question

[Pirate50]

Thanks nine8six. Yeah these are the Formulas ( 5 spoke ), I figured it would be touch and go on the fit. Offsets look as though they would work (w/spacers anyway) but it is the 10.5" width I am worried about. Saving receipt not an option since they are used. I don't very often see any Techart formulas that will come close to fitting a 986 in 18" for sale used and new are just too much.
