No, I'm not saying that, traction isn't really the issue it's finding tires that will last. I just waisted $90 on xo-1 tires and the grp's are $42 for four and have been proven in the speed run community to exceed 140+mph so I ordered some. I am interested in some foams but the grp's should easily take me to my current goal of 100mph. Later I might do 8s on a xl2 to hit higher speeds. Baby steps for me, I'm new to this. I'd like to see the foam tires and wheels though. Maybe I'll pick some up.
