Did you guys recalibrate the speedometer after you switched to a smaller diameter rims? It's not a big deal because when driving on smaller diameter tires, your speed is actually lower than what the car actually shows. So if you go with 130km/h on 18", you actually drive with 120km/h on 17"... Approximately, of course.

Just wondering.
