it shoudn't rub at stock height. If you're lowering or have weak springs you may get some contact with the front outer WW. I've heard guys running smaller BS like 4.5 (front only) and are still OK, but a little more gives you the option of lowering 1-2 inches. There is a lot of talk about BS w/18X9s over at the YO bandit forum:

SW's red TA was running (CL205s & TTIIs) 18x8f w/4.5"bs and 18x10r w/5.5bs with 255/40/18f and 295/35/18r just for a reference. I'm running a little more (.25") bs front and rear with 255/45/18f and 295/40/18 rear. I'd HIGHLY recommend you call Jon @ DriverzInc with your backspacing questions. He'll help you nail it the first time!!

18*9 in the front is a little big especialy if you have stock control arms. I think 18*8.5 would be enough and clear everything at a 4.5 BS. Just my opinion.
