How serious are you trying to be here? Let's be honest, tires are great, but is your skill there?
I'm in no way trying to say you aren't, I simply don't know. You'd be surprised what a decent set of summers (HTRZ3, Indy 500s) or even the budget tires that bump you into a different class (Nexus Sur4, federal rsrr, etc) can do. Are you competing for a trophy or national scca run? if not, I'd re-evaluate where you put your money, honestly.
