Dude Sport Max 006... Comes in 4-lug with up to 9.5" width... And they're not to terrible expensive for a decent racing lightweight wheel... sportmaxwheel.com
thats what i have.
17x9 rears and 17x8 fronts.
imo, theyre the perfect size because tires are reasonable and you can still get a wide and low profile tire with lots of sidewall for comfort and flex.
