Aesthetically, the 997 probably looks better on 19" wheels, but large wheels and tyres always detrimentally affect the way a 911 drives.
Thanks - yes you're right. Probably not a good idea in my case.If you're asking about your own car (a C4S iirc) that aesthetic is particularly important as 18" wheels on a wide bodied 997 would look a bit odd.
Porsche included 19" wheels as part of the C4S set up so I suspect changing to 18" would be detrimental to your particular car.
