Traction will of course break. Many reasons for this to happen. On a dead straight road, in summer with new tyres there is no real reason to spin up. But different roads, and there condition, the amount of throttle the curvature of the road including vertical etc can have an effect on a car OBVIOUSLY. How decent are the tyres?
Ive had Traction break and I spun the rear wheels at 115mph with everything disabled. Back end kicked out a little, was fun!
.... But I now have a M3 CS
