What 60' times do you drag radial guys get consistently? I have some 1.8's and others like distantpulse are getting 1.7's on street tires. It would take consistant 1.5's or so before I would spend the money. I ran drag radials on a extra set of tires on my last car and it was an aggravation swapping the wheels back and forth all the time.

The setups you guys have look nice though, I think the 16" wheel would be best since you get more sidewall on the tire and that usually equals more traction at the track.
