The 330 does not have the same level of torque, but you still are going to be unweighting the inside rear wheel.

Although I am a big fan of planning out an entire system and installing the whole thing one time (saving on labor and alignment in addition to having no weak links), in your case I suggest you try the M3 front control arms first, and some sticky tires. You can adjust under/oversteer balance with tire pressure, although that does not sound as sexy as a bigger rear sway.
I am definately doing the M3 front control arms.

I won't change the springs because it snows here and I don't want the car any lower.. and I drive about 20,000 miles a year so comfort is more important to me that the 6 or 8 auto x events I do.

My car does not have an open differential, I have a 3.64 lsd rear in it.
