look at the post above that, the yellow Boxster which has same bumper.

 

It appears to me that those rear spoilers would only tie into their wide-body kits.

 

then you need the 997 lights as well. My point was, I like the integrated design how the rear spoiler blends in with everything. I have yet to see a large (larger than your one) spoiler wing that looks as good on a 986 rear end.
