Is there a part number that anyone has, want to make sure I have the correct one. Is there more than one available? Any links or write-ups? I did some searching but didn't find anything substantive. I should probably start a new thread.
Thanks!

Post 154 for the M3 Vert rear bar part number.

Posts just above it have the standard M3 rear bar number which will work too (just not quite as stiff).
But again, the rear of the car is all E90. So any write-ups or parts for a RSB that fits an E90 (328/335/M3) will work.
I'll say this, if you ONLY do the vert or regular M3 bar, you can sag the sub-frame low enough without disconnecting the brake lines and wrestle the bar in there. A PITA, but it can be done without completely dropping it. I'm not sure if you go aftermarket M3 bar that you'll be able to squeeze it in without disconnecting the lines.
