Driving stability

Hello together, I am concerned with the stability at high speeds. Specifically, I have problems at high speeds with the car. Especially if the road has many unevennesses. You notice then a very nervous front axle / steering. To reach the 300 with it is then very difficult or you don’t feel safe. Also in the range 270. My V10+ has no dynamic steering and has pushed it onto these. However, you notice more that the Magnetic Ride the front axle I have read now that there is a specialist here in the forum who has a lot of experience with the R8 and could help with a different chassis accordingly. How are your experiences with another chassis that doesn’t come from Audi? Do you have any recommendations ? I imagine with Stabi`s and another chassis the R8 deutlic h to get quieter. I would be very happy about feedback, and to whom you could contact. Thank you!
