Hi all, i just order my M3 with 19"wheel (with no 18" offer in my country Hong Kong).

Here is my options

1) stock 19" on road and aftermarket 18" on track

2) try to swaps stock 19" to 18" for track used, and aftermarket 19" on road

3) stock 19" on track and aftermarket 19" on road.

Personally i would stick 19" on road as the better outlooked, but base on the performance wise on the track, i would perfer 18"on track (becuase i am not so sure if it is a good idea to use 19" on track) ......so it is a hard choice for me and it is kinda waste to have aftermarket 18" for track used only.......any suggestion? thanks alot~~ sorry if i just asked a silly question as i am new to BMW~~~
