I took the Duster out on the weekend with a fresh set of M/T ET Radials 726/60/15 (28") and the car all day ran 13.1's @ 106mph with crap 1.95-2.0 60ft times and it was spinning the boots every run. Tried a few different launches and the like and didn't work. I've scored a pair of Caltracs for it that should sort that issue out. Outside of that the car went beautifully. Nice and straight out of the hole (except the wheelspin) and was really happy overall except for the times. The new converter and shift kit have made a huge difference too.. Shifting at 6,000 and over the line at 5,800 and it was perfect! Just need to sort that 60ft time out and run again and then time for a 100 shot of gas...
