qa1's are junk imo, unless you get the dbl adjustable than i don't know but they have to be better. penske's would be real nice. don't know if it will make much difference with your higher rate springs though. if you want to try different tires you could go to stock car type, hoosier i believe, whatever they use on current round track stuff now and have a pretty good choice of compounds and priced competitively.
