Thanks! I looked up the compounds and would explain why Rampokker said his car pushed a little bit with 573. I have run 571/572 and 571/575 on carpet and asphalt with good success. I have run 574/575 on carpet and it works very well when the grip is lower. I want to try 574/572 next outdoor race day. Knowing that 573 is harder then 571, I think I will skip that compound. My head hurts now trying to keep these all straight.
