We dropped three tenths. Using 20 /46 compared to 20 /45 some serpent guys were using 19 / 45. It was the speed in the infield that made us faster not so much the straight. Good luck either way.tire sizes were low also giving optimum times. 65/72... low 16's. This was in December temps were high 70's low 80's ...
