For my C55, I've always changed my own tires/rims (winter, summer, and track tires), and I've been using a Michelin jack to raise the car for the last 3 years.
As you can see in the pics below, my current jack will not work for the 135i for 2 reasons: 1) the car is too low for the jack that I have, and 2) it won't fit into the rectangular plastic jack point on the car.
Obviously, I can try to get a jack that goes lower to fit (like the top of the line Michelin Aluminum Jack) to solve problem #1, but what do people suggest I do about problem #2? Do I have to fabricate a custom "insert" into the floor jack to fit into that rectangular jack point?
Also, do people know about anything BMW dealers can offer for this "problem"?
