Until 3 drunks pushed him together and I got now again a young used . This I have now a little nice again , and also again a field optimal The old bj.2021 for 188 kmh peak , The new BJ. 2020 only 175 kmh , The type has increased in the control unit 5 values which were in connection with the vmax , he really tried … We drove 3 times a big lap on the highway , but unfortunately without success .. 175 kmh end I now drive on the highway with full gas is like a full braking when it arrives at 175 kmh (Ironie) Through the chassis and the rims he also has a stable driving picture.
