One mount in particular (either the right front or right rear IIRC) tends to tear first as a result of the stresses induced by resisting the rotation of the tires and driveshaft (both are applied to the diff). These forces "basically" cause the sheet metal to completely tear.

The M3 has reinforced points, and I don't believe they were ever revised. On boosted cars, they can still tear, the best reinforcements I have seen involve welding a car across the trunk floor, and running a bolt all the way through the bar, letting the bar carry the load. Sheet metal (thicker) is also welded around the area on the bottom (from both the top and bottom) to help reinforce it.

The cars most prone are 1999 and 2000 E46's, and 2001 non M's. The problem is more present in manual cars as the jerky high stress loads are more common.
Thanks man for giving me more info on this issue.... This is really minor, people have made this problem out to be much bigger than it really is.

Well, its a pain to fix, and expensive to reinforce, but in the M3 its not as bad as its made out to be.

I have about 5 G's on my Z left to pay off and cant wait.. I definatly want an M car possibly an M3 or M5.. I've seen low mileage 06 M3 Verts going for 33k with 6 yr 100k warranty at dealerships out here...
By next year perhaps they'll be high 20's always wanted an M now soOo affordable

I consider that a compromised car as well.
I don't really consider that a supercar, although point taken.

I was meaning things like, lambo, Ferrari, Koenigsegg, Pagani, Ford GT.

Cars that are low production purpose built track ******. The 997 is made to be a trackable street car, same as the M3.
