Hi...I spent yesterday trying to figure this out too...on very similar track conditions by the sounds of it. I made progress, but not sure I'm 100% there yet.
I built the car using a bit of the Naoto setup from EOS, that setup really isn't meant for our tracks though, and a fair bit of a Maritime setup that got posted on Facebook, but have been gradually been adjusting things according to my own experience of it.
Will try and get my full setup posted at some point, see if it gives you some ideas.
But as a clue.....
Front end
#2 Pistons
AE 35wt oil
AE Yellow BB springs (stiffer than Yokomo X Reds, which are stiffer than kit!)
2 x limiters
Outer hole on tower, middle hole on wishbones
Ride height approx 20mm (not accurately measured!)
Rear End
#1 Pistons
AE 30wt oil
Yokomo blue long (kit) springs
2 x limiters
Inner hole on tower, middle hole on wishbones
Ride height approx 20mm (not accurately measured!)
Weight balance...
605g Front...30g under servo, 20g in front of servo
1039g Rear...75g under lipo
Tyres
New (at start of day) yellow low profile cut staggers
New (at start of day) yellow mini spikes, dboots medium (so chubby!) inserts
I've been using my old centro and it's setup as another reference point for this as it's not dissimilar in a lot of respects (other than the chassis obviously!).
I did some playing with the rear camber link...ended up with inner ball stud on outer holes (so short link), no spacers. Moving it out and down seemed to help catch the rear end on power off the apex's.
It still wasn't totally right by the end of the day, but it's pretty close now I think. Compared to other cars, I'm wondering if track conditions, tyre choice and my throttle control were factors in the loose rear end! At least one of the other cars running ahead of me was on minipins, which seemed to be an advantage.
I qualified 4th and finished 3rd in the A at WORM with that, and was on good pace for me, and running right on pace with the leaders through the day. Comparable to the Centro on a well developed setup when I last ran that, and this was only my first outing with the Bmax2 outdoors, so VERY happy with how it went!!
Will post back when I get the full setup on the sheet.
