Sliding on tarmac

It seems that there is to much longitudinal grip, it's was the same for the Dirt serie: if you touch the throttle once the car is set in the corner, sliding, the grip cut the slide and the car go straight in the middle of the corner instead of extending the slide. It's worse with RC1 car as the rear differential seems to never lock completely, what ever the setup you do : one wheel spin and the car stays stuck in the meddle of the airpin. It's so frustrating!!! And the same apply for gravel in a different way as the cars has way to much traction and you don't have to fight to much with the throttle to get out of an hair pin. I wonder why they implemented a traction control assistance...
