Sixpac, try using two of the small washer on each side of the pistons instead of one. We were having problems with the washer slightly getting bent and then the piston would tilt sideways and the suspension would do exactly what you are talking about. With the two washers on top and bottom of the pistons problem solved. We run #1 piston in the front with Losi 60wt and #2 with Cen 30wt in the rear on the stock TR.
