I just need a little help understanding a few measurements
OK, so here's the deal. I'm looking to get into a 17" set of wheels, and a little later I'll be going with disc brakes all the way around. My car is set up with a re-fitted 12 bolt out of a Chevelle, so it's about an inch wider than stock. Therefore, obviously, I can't use "out of the box" '69 Camaro measurements (which I hear is a bad idea anyway).
I got under there with a tape measure, and what I came up with was a 17x9" rim with 5.5" backspacing. However, in looking through the various combos in the sticky thread, I see a ton of guys running a 9.5" wide rim with a 5.5" backspacing. It seems to me that since I have a wider rearend, I should be able to run a similar rim width, but with more backspacing to fill up the wheel well (in theory, anyway). Can anyone help me understand?
On a separate note, running a non-stock rearend certainly limits your choices on wheels, unless you pony up the extra bucks for custom configurations!
