Slower is faster!
Sorry, I'm posting between meetings. But you are right, if he is traction rolling you'll want to slow down before corner entry and try different tires that are less sticky (or your ca trick), and also allow more sway for chassis to contain that horizontal energy.

I'd try lowering the center of gravity first, but worst case, I've found raising the car slightly and allowing more sway prevented traction rolling and hop.

I've made pancars traction roll on carpet so I know from experience just stiffening up the suspension may not simply be the solution.

By allowing more sway, you will definitely want the diff stiffer exiting the turn cause the inner wheel will try to start lifting off the ground.

I'll also check the track rules on aftermarket parts but considering a couple guys cars were pretty blinged out in blue anodized parts I'm guessing the track is prety loose on chassis hop ups as long as your using the Johnson motor and no speed gears. Last question before I start applying these great tips, shorty or full size lipo? I figured for weight purposes the shorty would be best so that's what I used for my first two races but I've heard some like the car better with a full size lipo just curious the benefit? Thanks again for the help.
Sounds good. For me, I'm going to say full sized Lipo's, but make sure the battery can clear the rectangular cut-out of the V2. My 5200 would not fit through the opening so I use the rounded housing Peak Lipo's on my V2. I have a 4200 Shorty too, but at least on my car, the car runs better with the extra weight of the full sized lipo's.

Hope some of my info helps..
