I have my car since end Jan and drove more than 3.000 KM already. Driving between 80-130km/h the steering wheel vibrated a lot. In March I went back to the dealer. After checking the wheels and tires they found out that the P-Zero were not well balanced and I got 4 new tires. After this procedure the vibrations were gone. But! When I drive between 140-180km/h the steering wheel is vibrating again. Driving 230-250km/h the whole front of the car is vibrating quite a lot. To drive above 300km/h the vibrations are very heavy and very curios ( compared with my 430Scuderia). Anyone with similar experience at high speed?
