I have been to Bandimere speed way with mine this year and I have 4500 miles on them and can say without a doubt they stick very well for 1/4 runs. I pulled a 12.8 on them at 5600' above sealevel. that is about 11.6 for you flat landers equivalent I am told. The humidity was non existant 7% and it was 88*f and 108 on the track and they did me proud. I am sure with some practice I could get another .2 out of them.
