Hi, I have send my car for alignment at 4 different shops. After alignment the car feels sharp but after 2-3 weeks the car handling becomes sloopy again. SC diagnosed it to have faulty suspension. After suspension replacement, the steering still feels vague at high speed. Any thoughts on my issue? One issue comes to my mind is faulty steering rack. All four tires are pirelli zero. Rear are few months old and fronts are 1.5 years old. I have more confident driving myvi at high speed than driving my f10. Quote disappointed with the handling at the moment.
