FWIW, I put 225/45-24 bfg dr's (brand new) on my car and pulled 2 2.1 60' times on a slippery, cold (40's) track 2 weeks ago (18 psi in the tires). Both were with the tires spinning as well, so imagine what a nice hot track would do. I'm well into 4th by the time I cross the line, but I'm also reasonably sure I can get sub 2.0 60' times with these. The grip is outstanding.
