this is from http://www.wheeldynamics.net/appguide.html
986 987
can use most wheels from the 996 with spacers in the rear. 40mm-65mm et front and 40-50mm et rear (stock 18x10 is 47mm) the 18x10et 65mm 996 wheel will require a 15mm spacer to clear the shock.
most extreme is the techart 18x10.5 et 42mm wheel for the rear. Use zip ties for the parking brake cable. 285/30/18 tire is about the largest you can use.
can use 19' from 987
most extreme fit 20x9 et50mm and 20x10 et 60mm(15mm spacer) with 245/30/20 and 285/20/20
20x9et 50mm and 20x10et 60mm below

It should not matter if it's a Cayman or a Cayman S. The issue is the offset of the wheel more than the width of the wheel. The Techart 19" Formula for the Cayman is 11" but the offset allows it to be used w/o rubbing w/ a 15mm spacer. I had these on my 06 CS and they just fit. That's probably where your seller got the idea that the 997 wheel would work, but the 997 wheels have a different offset that doesn't work w/ the 987 series. If the wheels stick out beyond the fender the car will not handle as well and looks bad. You should stop using the new wheels and put your old ones back on. If the seller won't take the wheels back you should try and sell them yourself or trade them in on wheels that will fit. Just chalk it up to experience, the teacher that gives the test before the lesson!
