jack stand fitting \ placement
I have a 2010 M3 - Love the car. being I live in the northeast I replace my summer wheels with winter snows. With my prior car and in the past with this car, I placed the the floor jack under the standard plastic fitting (sockets) for the bmw jack. With my old car this worked fine, but in my new car the plastic appears to be weaker and has deformed and cracked. Can these plastic jack stand sockets be easily replaced and equally important where do you recommend I place my floor jack to avoid this problem going forward.
