no in fast speed no problem you know we dont need steering in high speed but.when you break after turn left or right (for example 90 degree corner) 20 or 30 km speed.Maybe I need only 10-15 degree steering maneuver but not allowed.big force after suddenly turns.I hope you will understand.
and I guess it s about bearing.is it ??
