I was thinking of getting a set of takeoff 18" Cayman S wheels for winter tire use with my CS, but the Tire Rack-recommended Cup 3S wheels are a bit cheaper though they're not quite the same size:



What have other people been using?

Also, Tire Rack shows one 17" option for the Cayman S, where all the Porsche information I've seen says 17" wheels won't fit over the CS brakes.

What's the truth there? I like the idea of swapping my 19s for 17s for Winter/Snow use.
