I'm running the factory 17" wheels on my Boxster S - 225/45/17 (front) and 255/40/17 (rear.) I'm quite happy with the setup.

You'll need aftermarket adjustable drop links for the GT3 style sway bars. The stock ones won't work because they wont' reach the mounting holes and may potentially snap under excessive load and accelerated wear/tear.

I'm afraid I don't know anyone (personally) who runs a 275 or 285 size tire in the rear but hopefully someone on the forum can chime in.
