Getting a new yaris, couple ?'s

[Ronbo]

Sup all, first off i'm suprised there are forums for these cars heh (this was going to be my gas saver car )

I've been pricing out a 09 black 2dr hatchback and saw the TRD 18inch 5 spoke rims/TRD lowering springs...

18 inch rims on a little car like that sounds painful (drive quality wise), i noticed a good amount of posts discussing rims, but here's my question.

I don't really understand how rims/springs work, sounds silly to you all i'm sure. I noticed a set of konig feather rims on these forums (17 inch, 8 spoke).

- Would i need springs with these or do the factory ones work?
- Springs + low weight tires = Good ?
- Anyone have some pics with these rims?
- Anything i'm not thinking of in regards to buying this car (rim/spring wise)?

Thx
