The hitch mounts to a sturdy piece of the bumper assembly. For what I'm doing, max trailer weight of 1,000 lb with max tongue weight of a little more than 100 lbs, I have no concerns.
Pasted from stealthhitch:
The vehicle capacities with the BMW M2 trailer hitch are:
3,500 pounds - gross trailer weight (GTW)
250 pounds - tongue weight (TW)
