i run a COYS WHEEL, currently a 7" wide front with 4.25 BS, i would love it to have 4.5...
This is why the new "Speedway" wheel is so popular.
Billet Specialties decided to come up with an affordable wheel (aka Chinese made like all the other cheap wheels),.. that actually FIT most old cars and trucks.
THEY GOT THE BACKSPACE NUMBERS CORRECT,... when all the other companies were just guessing.
They come in gray centered wheels and full polished as shown below.
Contact member Way2lo2 here on the board or check them out at http://www.billetspecialties.com/whe...ies/speedway-/

I think Summit Racing even sells them.
