Hey, I'd definitely recommend having that looked at as there shouldn't be any sounds noticeable.

Did you have to cut the bump stop

There seems to be an issue with G42 rear suspension knocking - see https://g87.bimmerpost.com/forums/sh....php?t=1903609

How have they held up any strut issues?

Same question here seem like even a mild drop like eibach are killing stick active dampers or regular dampers very fast.

Sounds like coilovers are the way to go then?

I do not need the height adjustability and the cost of coilover that keep EDC is a bit high.


On my previous car, BMW 535i 2011, I installed my h&r spring when the car was 3 years old and I did 10 years with the stock shock without issue… just wish the G42 Monroe’s were as durable as those…

If Bilstein were selling a B8 Damptronic 4 shocks bundle for our car that would be great to pair with eibach when the stock shock start to leak. But my understanding is that you can only buy individual B6 damptronic at a not very good price.
