I have the same set of Hardrace 7260 rear trailing arm bushes on the shelf at the moment
Im going to use them with RTAB limiters that i got from FCPEuro.

Have them on the shelf waiting to go in aswell.
And for the smaller bushings/ balljoints, i mean the upper and lower one on the trailing arm... i have Lemförder balljoints in the mail arriving next week...
Same parts as in this FCPEuro kit, minus the monoball RTAB:

I did consider going monoball RTAB-s at first but then thought that its too much for road use.
Upper one im just replacing with a new one and lower one im upgrading from rubber bushing to the balljoint like the upper one already is. On e46 m3 or e85 z4m they are both balljoints stock.
Hard to find these Hardrace trailing arm bushings and limiters in EU. Hardrace has their own EU website but those bushings were not in stock and had a 3week shipping time
Finally found 1 set in stock at Atomic-shop located basically next to Nürburgring. And RTAB limiters i could not find anywhere in EU so ordered them from USA (FCPEuro)...
I still have a few things to order/arrive ... im also replacing front strut mounts and spring pads and front wheelbearings. Can probably take my Z to the shop for install in a week or 2.
Where did you get those chunkier mounting plates/carriers?
Im planning on using stock ones atm.. What is the benefit?
On the Hardrace RTAB-s and limiters theres a great video on youtube btw:
