I don't know how the AT w/ VDC on behaves when loading/launching and if it will bog you down like it does in the MT if you start to spin the tires. With the MT there is a sweet spot in launching with VDC on where you can get a good launch and maybe some slip but not bog down... Perhaps an experienced person with the AT can chime in. From my own reading, I've seen that most guys with the AT have no problems getting into low 13's so it can't be that hard. If you're comfortable and experienced with your car and RWD I would say just go for it with VDC OFF but we all know how many VDC OFF threads there are here
