Per this thread: "TSB #4407, dated March 4, 1997: " Eighteen inch wheels are not approved for use on Boxsters. Use of eighteen inch wheels on Boxsters under severe conditions may result in structural failures of the body and/or suspension".

So as long as you aren't tracking the car or doing anything really stupid with it I think you should be fine.
