Slicks with stock spring location? (I know I'm crazy)

my brother is running a 26x8-15 (hoosier quick time pro 26x9.5-15) on a 8" wheel on his 69 dart...no problem so far with rubbing etc.

I just sold my racing tires to a guy with a 72 dart, same tire as above on a 7" wheel with 3,75" BSP.....it fits very good and has very good traction at the strip. I have very good experience with the hoosier qtp in this size!
