Stock 1986 camaro, wondering if anyone runs a similar setup any if there will be any fitment issues?

 

Everything looks good to me. Bolt pattern, width, offset, overall tire diameter...you should be good! ....with a 275 on front, you might get a smidge of rubbing, but I think you'd be ok. That being said, a drag radial up front isn't exactly an ideal set up. It'll grab ruts in the road and the side wall isn't exactly designed to "handle" overly well.
