I just made the switch two weeks ago from a Hoosier Quick Time Pro to a Hoosier Drag radial 295/95 -15 on the recommendation of several friends. So far I only have about 12 runs on them but I like them as i can run more air pressure and they don`t need a big burnout. My 60 ft got a little lower maybe 1 or 2 hundreds but I also did a gear change from 4.10s to 4.30s. These runs have been in the heat as its been pretty hot the last few race days I am looking forward to see how they work in the cool, fall air, my 60fts have been consistent so far.
