V Max stability Cupra 5D 290

Happy Christmas dear community. On Saturday I made my Cupra run after 2500km on the A7 direction Hamburg. The car has the Eibach pro kit(incl. axle measurement),Conti TS850P winter tires up to 270km/h on original 19 inch Cupra rims installed. As everyone knows, the car with DSG in the 6th course at 6100 rpm to Tacho 272. It also reaches the Tacho 260 quite fast,if you can drive the 5th course to approx. 236 in Cupra mode manually. The car pulls saub He has a track and until about 255 there is no feeling of insecurity. However, I felt a very easy hopping of the front axle, as I mean. That became more and more with increasing speed. Not threatening but to feel! Do you have an idea what that can be? Look forward to your information! By the way, after now 2800 km in the Cupra I still do not mourn my M3 F80!
