No affiliation with the seller, but wondering if these would fit on an 03 Boxster S?
Would spacers be needed? I would prefer not using spacers if possible.

If one is to presume that the rear wheel is in fact 11 inches wide ( because the listing does not clearly state is), then no way, no how will a 986 Boxster accommodate a wheel of that width. Besides, for 4K plus there are far better wheel choices out there that will provide you with perfect a fitment in terms of sizes and offsets.
