Cargraphic Wheels fitment

[Wingnut2u]

New Boxster S owner here and ignorant when it comes to the technical side.

I just picked up a set of Cargraphic Racing Wheels but I forgot to check the offsets before I bought them. I also thought they were mounted on a 986 only to realize that they were on a 996. I got them for a good deal so even if the don't fit I should be able to resell them and not lose any money. I know the rear wheels are going to be a close call but here is what I have:

2001 Boxster S (stock)

Cargraphic 18" Racing Wheels

front 18 x 8.5 et 37
rear 18 x10.5 et 52

Will these fit and what size spacers will I need?

Thanks
