About to buy wheels, '48 s10 swapped

[Dustint]

I've narrowed my wheel choice down to coy c5's. Was originally planning on going with boss 338's and although the coys are more pricey I like the styling differences better. I've done quite a bit of reading on s10 sites concerning backspacing, size, etc.
From that I've narrowed it down to two options for the front, the rear will be 20x10
The front either 20x8.5 with 4.75" backspacing or 20x7 with 4.25" backspacing.
I'd prefer to run the 8.5 width if I won't run into any (severe) rubbing issues, from my research on the s10 forums the 8.5's should be doable as far as suspension/frame is concerned. Anyone able to weigh in on what they are running? Really want to confirm my thoughts on the 8.5 before dropping money on wheels.
