where to buy: subframe reinforcement plates?
I spent 3 days working on an e36 where the subframe/differential tore out of the body of the vehicle... the damage was horrible, and I know it's only a matter of time before my car suffers the same fate, so I guess I'll have to drop some coin on preventive maintenance.
... where'd you guys yet your subframe reinforcement plates? I guess while I'm at it, I'll upgrade to a 325 subframe and drivetrain from the tranny back.

The subframe is a removable part of chassis. The rear subframe holds the suspension control arms, swaybar, and the differential, the front subframe has the control arm and engine mounted to it.

93 325i. The subframe took parts of the car frame with in for 3 of the mounts, the 4th one has hairline cracks. Once there are holes, it's a messy job to repair.

That's what I'm worried about... how bad was your damage? Did you just weld new plates on, or did you do it the BMW dealership way with a new trunk floor?

Ah-ha! I knew it! I called Maranello and they thought I was on crack.. I talked to 3 people, and they all said there is no such thing... I need to buy a complete trunk floor which continues to the frame for the rear seats, and weld that in place. I ended up making my own reinforcement plates for that vehicle (stock 325i)... for my car I'd rather buy the real deal. I'll let you know on the pricing tomorrow.

yes, very expensive unfortunately. not because it is difficult to do, but because it is a very time consuming and labour intensive process, since you have to remove your entire rear end to do it (exhaust, trailing arms, swaybar, differential, rear subframe, drive shaft, gas tank, etc.) to weld the reinforcement plates properly. It is also recommended that you remove your rear seats to prevent a possible fire hazard or melting of your leather/leatherette while welding. It is possible to DIY, as I plan on doing it myself. But it would be mighty tough without a hoist at your disposal. These reinforcement plates are stock on M3's.
The reinforcement plates:
Notice the crack? Time to disassemble the rear end.
Entire rear end removed, gas tank has been lowered, but not removed. This is a fire hazard though and not recommended. Notice the rust forming around the subframe mounting points.
Prep the area, ready for welding the reinforcement plates.
Reinforcement plates welded in place, and spray painted with underbody to help prevent corrosion:

possibly, though chances are it's your rear shock mounts, or trailing arm bushings... or even just the car jack in your trunk not being secured properly.
