I had the same problem last weekend at VIR. I think mine was from tires. 305 S-04's in back, the soft side wall and the over sized tire on stock Rays was rolling over a bit more than the OEM Potenza's. I will run with VDC off next time. And hopefully have a more suited tire. What tires are you running? I'm curious to here how it goes for you with it off.
