Thanks guys for the response. That answered my question, looks like 4.75 it is.

I always run 2 sets of rims and tires for my street strip cars. My Trans am had 17x9 and 17x10.5 for the street and 15" drag lites for the track.

I like black steelies and wide whites look on my 66 for the street but I want to have a set of 15x10s and 15x4.5s for the track. I will probably run some M/T drag radials 325/50/15s out back.

not really sure what rim i will go with for the drag setup. It can wait for a while anyways.

I thought about cragar s/s for the track but might go to a modern/light type of drag rim
