Backspace question

[aquickv6]

What is the correct backspace to run with a Weld Pro Star 15x10?

I think it's 5.5" with the frame notch done. I want to run the 325 Drag radials on the street, and the widest 28" slick at the track.

Anyone doing this?

i have a 15x10 with 5.5 with my frame notched and do need to space it back out, I would think 5" would be ideal,but weld does not make 5" backspace, Centerline wheels come in 5" though.
I am going to use aluminum drums to help, But need to wait till my new tires arrive to do final fitment

Otto,

Thanks for the reply. What size tire will you run for street and for the track with the 15x10 (5.5") ?

Currently i have ET streets, 28x10.5. I have on order 29.5x10.5.
I have yet to install any other tire as i just got the rims right before winter.
