KW Clubsport, track users

Hey, so I have a 2015 M235i with KW Clubsport 2-way. I am looking for some help setting them up properly.

I have taken the car to 3 track days so far, and it feels amazing, minus one issue I am having. When I hit any imperfections in the pavement, it feels like the car in underdampened (?). The car will shift what feels like weight side to side really aggressively and upsets traction, ultimately leading to me having to lift to re-stabilize the chassis.

I have the dampening set to the KW recomendations, but it seems like something is off. The car was corner weighed, and I minimally lowered the car. Tires are 255 rear, 245 front, Toyo R888R.

Anyone with more track experience than me that is willing to help out, I would greatly appreciate it.

Yes, what you're describing sounds like underdamping. If it feels like the whole chasis is swaying side to side too much, I'd probably try an extra click or two of rebound on all 4 corners.
Depending on how extreme it is, an extra click of bump could help too.

(I used to run KW V3s on similar tire specs and the recommended settings were definitely on the too soft side.)

Check they aren't leaking.
A friend had 3 KW clubsports and three out of four shocks blew quickly and they stuffed him around for months promising replacements before he got a refund.
