Streets & AutoX
Requirements:
lighter wheels - function > form, though looking good is a definite plus.
Perfect Flush
Square Set up
My option:
Looking at 18x8.5 with 245/40, offset: +42 Front, +32 Rear, no Camber
Taken this from the Wheels Directory post Darren started but I am wondering if the offsets are a bit too much for the front?
Also I am wondering if that tire is too skinny for the power I am putting down. I don't want to kill gas mileage as well.
Any sort of suggestions?

What @
swarb said about the tires is correct.
It's about total diameter, so as you go wider you need to go with a shorter sidewall number to match the ideal diameter. For speedo accuracy, you want to stay within 5% max, but close as possible to stock.
OEM diameter for 215/45R17 is 24.6"
- 225/40R18 - pretty close, 25.1", 7.5-9" wheel
- 235/40R18 - bit tall but okay 25.4", 8-9.5" wheel
- 245/35R18 - just about perfect 24.8", 8-9.5" wheel
- 255/35R18 - pretty close but still okay, 25.0", 8.5-10" wheel
- 265/35R18 - even taller but doable, 25.3", 9-10.5" wheel
- 275/35R18 - tall but within 5%, 25.6", 9-11" wheel
- 285/30R18 - close to perfect OEM diameter, 24.7", 9.5-10.5" wheel
What is your suspension setup? Stock, lowering springs or coilovers, camber settings?
