I had initially bought the Z4 M40i strut braces with the mind to fix them with nuts and bolts like the BMS/Dinan braces. After seeing that thread I bought 51648491817 "connection upper rear" from the M440i which goes under the slam panel and has nuts welded on so no need to faff around with using/losing a loose nut.

I did this mod to my M340i, the single best mod to improve cornering.

My 2022 M440i (convertible, but I'm sure it's same as the coupe on this point) has these strut braces from the factory, which are also fixed at each end by a single bolt:

My 2021 430i coupe has them as well.

Do you have a link for this? I put m3 g80 strut bars on my m340 but the V bar touches the throttle body, so I have to find another brace. I think this one would work well.
