Spherical/monoball for front control arm?

Putting Ohlins R/T in my car and looking to replace the front control arms as well.

Saw the Spherical/Monoball bushing from Turner or German Auto Solutions, like the idea that it can sharpens the handling(most likely won't track the car more than once a year, but do like sharper handling cars)

Have anyone tried those before? Worth the upgrade compared to new OEM control arms?

Lots of feedback on monoballs in this forum. You will see sharper turn in and less dive on braking but it's not a night and day difference.

The GAS ones have good reviews, I run the GAS ones. Turner ones wear out fast and are noisy. If I were to do it all over again I might go BW cos they look like they're easily serviceable.

Very happy with my GAS monoballs on stock arms. Steering feels a bit heavier with more feedback. Also helped eliminate some steering wheel vibration I was experiencing. It does slightly increase harshness.

Thanks!
Was debating between the Turner and GAS pre-installed ones, I will probably go with the GAS then! Doesn't look like BW sell any pre-installed

Thanks! I would be happy to endure slightly more harshness and get heavier, more feedback, and less vibration steering in return. Heavier and more feedback steering feels right on a M car lol

Just wanted to note that I ran another brand previously and had them installed on my existing arms on a prior M3, ended up getting some clicking from the front end after only a few weeks. Did it right this time and went with GAS on my current car, who understands that you need to use new arms or take incredible care with the install. Went with new arms this time after my prior experience, quite happy with GAS.
