Teach me about ITR 325's

[Olson-RRT]

Except, unfortunately, that's illegal.

Where the rear sub-frame attaches should be reinforced (many rip out) and having rust there will make this a miserable job.

Not if it matches the factory repair which has been close to an outright recall for the e46. At a certain point in their production cycle, both e36 and e46 chassis had this from the factory. Rust and wear can still wreck the factory reinforcements though. Not seam welding or anything along those lines, this is installing OEM parts. I don't think this violates item 8 under Suspension Mounting Points. I would not race an e36 chassis without these parts installed.

edit: Item H under 8. Body/Structure
All chassis/structural/electrical repair, if performed, shall be in concurrence with factory procedures, specifications, and dimensions. Unless specifically authorized by the manufacturer for repair or allowed by these rules, no reinforcement, i.e., seam welding, material addition, etc., is permitted.

Knew it was in there somewhere.
