This was me, pulling 1.39 sec 60' a few years ago:
Trust me when I say that being on the top of AWD launching game is NOT any easier than being on the top of the RWD launching game! It is easier to cut better 60' times on AWD when compared to RWD (with street tires), but that isn't saying much.
BTW, this launch and subsequent 10.0 second run, results in 0-60 time of around 2.1-2.2 seconds.
