I have the Senton V2 and mods that i made was other tyres, harder shock springs, and the diff fluid i changed a time ago. i don`t know now which fluid thickness i put in. The Senton now on gravel and sand sticks to the ground and in the turns he don`t comes around with the rear. I want to make him a little more a drifter in the rear for more driving fun on sand or street. How can i do this?
