I run a true 14 wide 32.5 tall Hoosier slick with a 4:30 gear trap out about 130mph at around 7000rpm. That's also the biggest slick I found for a 12" wide rim and they are a but too wide and I have to run the back a bit higher than I like, next time I'll be going with a true 12 wide tread to bring the section width down. I run a narrowed 9" with a 4 link and stock frame rails.
Color choice all owner preference but a a nice medium blue would look good.
Here is a pic showing that the rear tires are a bit too wide, watch the actual specs of the tire vs the numbers on the side, I've ran a 31x16 ET Street and they only measured 12" on the tread width.
