Wes-
St24 require 0.5 to 0.7mm of more shim than prior balls. I'd recommend looking at prior asphalt setups (for specific tires) and adjusting accordingly.
Some FL and CA boys will be running those new shocks outdoors soon (or have already) and can chime in on oil/damper settings.
As for MM2- I've only run mode 1 myself. Others are running mode 3. Haven't tested these back to back yet..
