Man thats a nice looking track.
Setup wise, your look pretty solid, some of the things I would try are as follows;
-If it felt good with the 2.0/2.0 try running with some 1mm hex spacers in the front and .5mm spacers in the rear.
-If you can either try the super flexi 2.0mm top deck or mod your existing deck like Ed/Tryhard did, a couple pages back, I think this shows great promise on carpet as well.
-try the lighter springs, maybe run the same ones front and rear.
-up the front diff fluid to 500k.
-if you have the V1/V2 motor mounts I'd play with that combo, again Eds post from before.....the only thing I found was my car worked better with running the top 4 rear screws, no middle screw, and the lower screw in the rear instead of the front.
-I'd still try running with out the bars, they can really mess a good setup up.
-The rest is just chasing the setup with doping the tires, maybe the entire front at the start of the day and then reduce as the feel changes.
-Oh and definitely go to the anti-dive in the front, that's going to really, really help settle the back of the car.
Let us know what works for you. (nice track
