So I have a well used E-revo and my buddy just bought a brand new one. The only difference in the 2 trucks is I run the e-maxx tires and wheels and I have the Variable Damping Kit (VDK) with 45w. shock oil. He is running 40w. and stock tires. We both use the blue/silver springs and everything else is pretty well stock. His car is on its roof more than it is on its wheels. My car handles like a champ. It very seldom rolls and will fly through a corner, Does the VDK make that big of a difference or is it the tires? He hates it so bad he is ready to throw it in a dumpster somewhere!
