So I did my searching but no one seemed to answer a very obvious question. Which will handle better? 215/35/18 or 205/45/17?

I am thinking the 18s will be better, but I need reassurance ...

 

Barely no difference in the two widths you mentioned. So handling wouldn't be affected much. The 215 will give a marginal increase from the 205 but not that much.

As for looks if you ever decide to get a body kit 18's will look a whole lot better. 17's will end up looking like 15's

 

18's would look better, but are more expensive and heavier...............are you sure they would fit fine ??

 

Yeah. 19's will fit if you can get a high enough offset. Someone the works for Rishie's got Giovanna's in 19's. Looks good too.

 

18s or bigger
