*Update*
So…
Misha did a lap in my M240 and we made a video so stay tuned for that ! He is a much faster driver than me (obviously) and he had some positive feed back and some takeaways. I did an additional lap afterward just to get one more in before track closed.
Tires: started with 2.0 bar F & 2.1 bar R. Worked perfectly
Tires hot got to 2.8bar which is perfect.
His positives : power is perfect and the car obviously more RWD biased than the previous Xdrive models and the M Performance LSD helps out tremendously.
His takeaways: weight (given), car tends to oversteer but we may be able to correct this with a track alignment. For the Brakes just step up to a better pad, suspension is too soft for the weight of the car.
Keep in mind this is the Nordschleife which is extremely bumpy , has a few jumps and major elevation changes. So tailor your alignment to the track you drive on.
Final Thoughts: with some light modifications this car has major potential. Our only drawback here is the weight unfortunately.
