Mine is the rtr sr10m. I put custom works springs in it and added some weight to the left front bumper, left side chassis stiffener, beside the gear cover, and directly behind the drivetrain case. For springs it's a yellow cw on left front, grey cw on right front and left rear, and deep red cw on right rear. What compound of tires are you running? I ran jconcept twin peaks in pink compound on hard packed clay and did well with slight pushing.
