I have the new Lemforder arms + G.A.S. monoballs. Here are my thoughts after 1 year of use:
1. I replaced all my steering linkages and other joints along installing KWv3 suspension. Despite proper bed-in procedure of brakes, i still had intermittent vibration on braking. Not all the time, but sometimes it would happen. This has been completely eliminated since upgrading to monoballs
2. The steering feel is just awesome. Is there additional NVH? Sure...but its barely there....maybe 5% more? I don't even notice it now. My car feel so planted and precise...I absolutely love it.
3. Sometimes at large steering angles / articulation i can get a little bit of creaking / popping sounds. This rarely happens, but every so often I will get it. Not a show stopper, but just being transparent.
The Verdict : Do the Monoballs and say goodbye to numb steering and annoying vibrations from braking. Seriously. If I were to buy another M5 this would be one of the very first mods I would do.
