Awful handling. Something is definitely off.

Punched out RTAB caused by what? How common is this?

60k miles +/- seem to be a normal interval for the RTABs. When I was at the dealership this was often times missed by guys on the Inspection 2 service, then you'd have a client come right back saying the car drivers poorly or the tires have accelerated wear. It was so bad that if a tech missed it they were making them buy the tires, lol.

Essentially the rubber fails and the trailing arm can move fully sided to side in the RTAB bracket, this causes such a large toe change that the car will crab walk or rear steer. The toe irregularity will quickly wipe out a set of tires.

Following to hear the results - Good luck OP, sounds like you've got a parts list that will be solving this, and curious to know what you find once the work begins!

Are you running Hankook V12s? If so, that's the issue.

If not, I'd suspect and RTAB issue before anything else.

... and if it's not that, check your subframe mount points.

Haha I hated my V12's so much. But they didn't yield any of these weird handling traits, just a vague/sloppy steering.

The issues OP describes sounds like RTABs or alignment. When "pushing it" RTABs rear their ugly head because the rear of the car steers where it wants to. The wandering front end can be alignment, or steering related (FCAB, tie rods, ball joints)

I've seen similar issues happen with belt separation in tires
