I ran the Street R's on my 67 Cuda for a season of racing and "drag-n-drive". My car runs very low 11's (11.1), and a best 60ft of 1.49.
the tires held up all season with drag racing and the drag and drive street driving. I ran tubes in mine, and had the pressure down in the 17lb range for some tracks. I use DA shocks, and Smith Racecraft Assassin traction bars.

(I realize that my car is probably slow compared to your combos!)
