Best size front tire/ wheel for C43?

[supersparker]

What is the best size front wheel/tire for a lowered C43? last week I ordered and mounted (2) 18X9" Monoblock II wheels with 235/40/18" S03's only to find out they wont fit on the front of my car once it's lowered.The Tire Rack said they could not take them back. have these for sale if anybody is interested....

Thanks,

the tire would most likely fit but the wheel is too wide max 18X8.5 if they recomended that they should take them back.
