i picked up a set of wheels with some nearly new bfg drag radials on them 205/50/15. i have never used any type of slicks or drag tires before so i wanted to get some advice before i take it to the track. what air pressure should i air them down to at the track? proper technique to heat them up? how much spinning? what kind of 60ft time can i expect? i run 2.3s on street tires.
