Set of wheels available near me with the specs in title. These would actually go on an '80 Trans Am but generally same as a Camaro. Thoughts on the backspacing? Was interested in at least a 285/40R17 in the rear, maybe in the front too if they'll fit. Have access to a 17X9.5 wheel w/5.5BS with a 285/40R17 on it. Thinking of using it to test fit. Used the calculator in the sticky and if I'm reading it right, the 17x9.5 will move outboard by about 0.3" in comparison to the 17X9. Should be good for a mock up comparison?
