I think millzy hit the nail on the head, you need more camber all round. The thin oil results in quick weight transfere, resulting in quick camber change. So when you are cornering with the little bumps and ruts you travel to min camber and then experience traction roll.
A lower roll centre as mentioned above would also aid in your current situation.
Also, tires have a big impact, so try tire with a very round shoulder profile.
