Also if you do want 17's then it's not like a cardinal sin or something. The Enkei MM2 is $187 in 17" for example and still isn't *too* heavy. Some other choices in 17":
5Zigen MK-5 - $192 @ discounttiredirect.com
5Zigen MK-6 - $192 @ discounttiredirect.com
5Zigen Super Six - $200 @ discounttiredirect.com
Enkei Bortex RPM2 - $222 @ discounttiredirect.com
G Games 77 Wolf - $234 @ discounttiredirect.com
For tires I would get Kumho Ecsta MX in 205/40-17 for $93 a pop from tirerack.com.
