85 Wheel fitment

I searched this wheel forum including archives, and couldn't really find any info. Any info is appreciated.

I'm trying to find a set for less than a grand, just to hold me over for 4 more years til I upgrade to a C5 or 6. Option 1: I like the ZR1 look, 9.5 front 11 rear, but everyone has them. Option 2: I like the 10.5 Z06 wheels also, will they fit on all 4 corners? According to c4 tech tips, the factory 8.5" wheels and the Z06 rears are within .05" backspacing... Option 3: I've found a few places to order custom wheels, assuming any wheel I order has the same backspacing as factory, they should fit no problem, right? 17" vs. 18" shouldn't make a difference other than tire size, right? What would be the maximum discrepancy in backspacing I could get away with? half inch? less? Any other options or suggestions? Sorry for so many q's, just want to get all the facts I can before I order! Cheers!
