Hi all
Just fitted these on my m550i
- Dinan monoballs on thrust arms
- f90 rear reinforcements, rear tunnel connecting plate and cross brace connecting tunnel plate with rear subframe.
Part list:
M5 Reinforcement for body, rear:

M5 Underbody paneling, rear:

I had previously fitted the f90 front strut bar.
Dinan product is top notch, superb quality. Expensive too.
I have only done 20km back from the shop, city driving on bad roads mostly, so will report back later with more distance behind.
But it's immediately clear that the steering vagueness that was bothering me is gone. steering feedback is night and day, along with expected increase in harshness - no noise or vibration but joints or cracks on the road are much more noticeable to me. I don't think that would be bothering passengers though, and i was prepared to trade this for steering precision so i'm fine with it.
