GTS rims, tire size Options

[hitcachi]

So im going to be wrapping my 7th gen GTS rims with tires this week. They are 16x6.5 wide. I was thinkin, maybe, possibly, trying to fit a 225/45 tire on them.

Would this work? Manny? I want a wide tire for auto x events and what not. OR, would i be better off going with a 215/45 tire. Another thing that i should add is, i have a pretty big drop thanks to the intrax lowering springs. But they are only 16's. Last question. Currently, i have the stock 15 BBS wheels on there with beefy 205/65 tires on. Would the 225/45/16 tire lower the car more due to a reduced side wall? If so, that would be awesome. Well let me know what you think. Thanks.
