What Rear Tire and Wheel Combo are You Running at the Track?

  • Sponsors (?)


505rwhp on a Mustang dyno. Probably a hair more now since we've made some changes to the tune. 11psi of boost on a 6 rib setup. Little belt slip in the higher rpms. We have an 8 rib conversion in the works.

How well are these working for you? What are your 60ft times and how are you launching on these? Thanks for replying.
I went from averaging 2.1's to averaging 1.9's, my best is a 1.89 running them at 25 psi. I'm sure their is more to be gained if I lower the pressure more. Pretty much leaving with a 3k clutch drop.
