What backspacing for a 12" wheel?
 

My friend is gonna get his car minitubbed and narrow the rear about 3" per side what backspacing would be required on a 15x12 wheel?

Any help is appreciated. Thanks!

on my car i have narrowed the rear 5 1/2 " per side and i run the 15*12 with a 4" bs. it leaves about 1" clearance between the 28*10.5*15W slick and the billingsley offset lower control arms.

Thanks man!

Tom did you go 15x12 this year?

i went to the 12 at the end of last year. it made the contact patch of the tire almost
2" wider.

Why don't you take some pics and send them to me.

why not post the pics. :)

ill get some pics taken and post them soon

Still sending pics? It's August. :)

I'll see if Madman has finished narrowing the rear for my buddy. He will be running a 15x12 with 4" b.s.

Quit your :cry: Jon

Now did that keep the lower control arm in the stock location still?

Thats what Im wondering? Im running a 315 60 15 Mickey drag radial, 3" narrowed per side and 5 1/2" back space. The tire is 1/4-3/8" from the offset control arm and 3/8-1/2" from the outside of the wheel well. How could a 12" rim fit? What tire are you running?

yes the lca was kept in the stock location. the rear has been narrowed 5 1/2 inches per side. and i run the billingsley off set lower control arms. they clear the tires with about 1/4 inch to spare with the 28*10.5*15 W ET drags. the 15*12 with the 4 "bs
