I did glue the front side walls. This helped a little, but not enough. I will see what I can come up with for stiffing the chassis. I assume that I should reduce the twisting of the chassis from side to side? What would be a good starting point for pistons and oil? I have 4 hole 1.1's with 27.5 wt Losi front and rear. 2.7 springs in front and 2.6 springs in the rear.
