You can get the up on two wheels though. Deep forest Reverse with a quick car will definitely get you on two wheels, especially on the back straight on the mountain.
I think most people here have the opposite affect as the OP. Cars roll pretty easy, especially with stock/soft suspension.
I saw an ai get on its front 2 wheels under heavy braking at cote azur(?). I was right behind it at the hard right before the tunnel and his back end went about 3 feet in the air. Looked funny on replay!!
