Waiting for my 57, 210 to be delivered from Illinois. It should be here tomorrow morning.
It nas new 15" Cragar SS wheels now, but Cragar has a Model 391 that is similar to the American Salt flats model.
What is the correct backspacing for this car if I go with 15"x7" wheels.
Thanks in advance!
Rick

Are you going 15x7 front and rear? What size tires? Is the suspension/brakes and rearend width stock? In the rear you generally want to go with a zer-offset wheel, which is 4" backspacing for a 7" wheel with a stock rearend. In the front it depends on your spindles/brakes and tire size.

Thanks for the quick response.
It's got a stock rear with drums, and disc brakes in the front. I was going to go with 15x7 front and rear.
