Hi, how can I have top speed with selection car, it stopped at 270 km/h but the adversary go more fast .
Top Speed depends on multiple things. For example, Döttinger Höhe at Nordschleife is not really suitable for top speed measuring, 'cause it goes uphill. So try it on an fairly even or downhill straight. The bigger "Problem" is aero drag. To lower it, you'll have to start fiddling with the car's Setup, for example by lowering the wings, lowering ride height; changing the gear ratios sometimes can result in higher top speed as well... However, top speed most of the time is not nearly as crucial as acceleration
