Next upgrade for 335xi rear suspension?

Here's my complete suspension setup and wondering if anyone has any suggestions what should be upgraded next. If this was your car, what would you do?

Overall I'm really happy with it but occasionally get a slight side/side shimmy over expansion joints. Car is a 2011 335xi with 65k miles. Everything is tight and in really good shape. I don't drive it much in the winter since it's a second car.

Front/Rear:
Dinan Springs
Koni Yellows
Dinan ride quality kit, new bump stops, etc.

Front:
UUC Front Sway Bar
Poly control arm bushings

Rear:
Turner Delrin subframe bushings
Turner Delrin differential bushings
BMS differential lock down brace
E90 M3 sway bar
BMW Group N toe arm bushings
E93 M3 rear subframe brace

Don't necessarily mind swaping bushings but OK spending a bit more to avoid having to cut/press out old bushings.


Couple things I've looked at:
-E90 M3 front Strut brace
-Turner Spherical Control Arm bushings (already have Poly though)
-Dinan Camber Plates
-Rear TRW M3 upper control arms
-RTAB poly bushings

Remember to REPLACE rear Frame Bolts as soon as you take them back out.
Reusing them can cause them to snap in place. Same goes to just about any aluminum bolt on the car.
For rear upper control arm, consider adjustable ones for easy camber adjustment. They come with ball joints.

Extra front camber will make a significant difference. It was the first thing I did to both my cars using the Dinan plates. Our cars come from the factory set to understeer like pigs. Will also allow installing wider front tires without rubbing the fenders.

Thanks guys. I ordered a set of Dinan camber plates this morning.

Any other glaring weak points? I feel like I've addressed most of them.
