What’s the purpose of thicker sway bar since the car comes with stock sway bar?
Also you don’t install front lower strut brace?
Thanks.

Even since my wife and I committed to our BMW being our daily driver/family trip car I have been on a mission to make it as smooth and comfortable as possible while still handling amazingly. Below is the mod list to accomplish this:
Koni Special Active Struts/Shocks
Eibach Springs
If >50k miles, replace stock rubber spring perches, etc.
18” wheels, square setup
1st) Stock BMW 400M 18x8.0
with 245/40-18
Later) Apex 18x8.5
255/40-18
Michelin Pilot Sport 4S
If I was going all seasons: Conti DWS06+
The Apex/MPS4S setup cuts 11+ lbs/corner of rotating mass for better acceleration and handling.
Also for handling & steering:
H&R Front 28mm sway bar
KC Design Rear 17mm sway bar
Weichers Front Strut Brace
VAC Monoball Front Upper & Lower Control Arms
KC Design Adjustable Sway Bar Links
I started with the Koni Special Actives, Eibach Springs and square non-runflat MPS4S 245/40-18, and the ride improved tremendously.
Hope this helps!
