are you class racing or bracket racing?
Tire choice is influenced by venue, class, power, suspension, trans brake or footbrake launch, track, budget and even demographics.
My experience with Phoenix years ago was not good as the tires don't hold air and were on the rims within 48 hours.
I've tried them all over the past 20 years and for me, bracket racing, none better than Hoosier when the criteria is consistency, usable tire life and able to hold air.
I've been running Hoosier Radial slicks for the past 11 years both the 30 x 10.5 and 32 x 13.5 and wouldn't run anything else.
Deadly consistent tire with the 60 foots varying thousanths from pass to pass with a 1.17 best and they don't leak air.
