The stock setup for the Yokomo YD-2 is for asphalt with the following changes it should do well on concrete.
-front damper moved inwards 1 hole top and bottom
-rear dampers top hole moved inwards 1 hole
-rear toe 2deg
-RR susp. block raised 2mm – allows more squat on acceleration and decreases pitching when of throttle ..
-rear camber 3
-front camber 5
-filled up the geared diff to only half so its looser!!
Haven’t tried this setup yet but I will
