So I have a 2000 BMW M5 with 120k I've searched forums and the closest I could find to this problem is the flex disc or guibo.....
Anytime under hard acceleration in 1st or 2nd gear I get a bad vibration, not really existent in the other gears....
Here is a link of the shake in the car
Any help would be appreciated
Thanks guys
Sorry if I posted in the wrong area.
