15 M3: Options to improve steering feel?

Any update?

Yes! Had the Dinan Strut Ball Joint Kit installed last Monday. It's been a week now and I'm loving it!

First impressions are positive. The Dinan Strut Ball Joint Kit is most noticeable at higher speeds and uneven dips/curves. Front end feels more planted and has eliminated the deflection when the front suspension is under load. Because the front end feels more planted, I've noticed the deflection in the rear more. It's like the rear end is twitching around while the front section remains evenly planted. My guess is the rear toe links will eliminate all that while increasing traction.

I've been driving around on various surfaces (new and old asphalt & concrete) and have noticed very minimal NVH. Most of which are induced on concrete bridges/overpasses, or very rough roads. On the expressway, asphalt, etc. it's as quiet as OEM.

I've also learned that the Dinan Strut Ball Joint Kit is basically a repurposed OEM BMW ball joints from the rear suspension with a CNC'ed aluminum housing.

*NOTE: The OEM rubber strut bushings are compressed and not reusable. Once they are removed, they cannot be re-install.

Attached a pic in case anyone is wondering what is included in the Dinan Strut Ball Joint Kit.

I have the Fall Line bearings for my car. Steering feel improved but the biggest difference I've noticed is reduced brake judder.

The steering feels fine to me!

Sorry to bring up an old thread, but I've been searching your post came up. Hope you are still around on the forums

Do the Fall Line monoballs have a seal? My car is driven year round in the sun and in the snow, would it be a concern?

Any one runs these bushings/bearing along with GTS steering coding? I'm running the Thor GTS flash on everything and there was a noticeable improvement on steering, but would like to enhance it more.

After installing Dinan monoballs I also feel more of the front end and it overpowers whatever the rear is transmitting. Did you ever install rear toe links?

I use SPL solid, eccentric castor bushings. I have increased castor angle a little and the solid bushings improves the feel together with a better steering input. A bit more roadnoice but so far i can live with it.

Not yet. Still debating on which ones I want to go with. Dinan's are still on my list. Picked up a new truck in the interim and that has been my new project.
