Fast, faster, fastest?

No offence but If you truly believe there are no negative effects to the handling of the car by going to 20" then you really need to do your homework properly....especially if you like driving at 300kph and expect the car to feel planted. I would also agree with the other member who said once you've driven at that speed regularly it becomes not such a big deal....but that said you need the car to be set up correctly for that. The bottom line on that point is you need to decide whether you prefer showboating around town or if you prefer getting the best out of your cars performance envelope. Just saying... after all the Porsche was essentially designed as a high performance package, and once you change things away from that set standard there are going to be implications, don't kid yourself.
