I run MT 325's on my Dart, if the track is good their great, if the track is marginal they suck. Most tracks around here don't spend much time on prep so I put a CRT trans brake that can leave in first or second in my transmission.
I accidentally left in second one time, with the two step at 2500 it sounded like a loaded dump truck taking off, it still went 1.51 60' though.
