Yellow:
Don't know if this has been mentioned, but outdoors I tried greens in the rear too and it mellowed out. Also, make sure you are only running a spacer under the t-plate in the back on the side for a total of 2 and remove the center one. It will allow the rear to feel softer. Make sure you are running .063" plate. Also run 0 degree of toe out in front, only sauce back tires, and finally go with 0 or 5 degree reactive caster, 10 is too twitchy.
