Solara. Thank you! I did not think of confirming there was something wrong with the rear diff. I did shim it when building! I will rebuild the rear end. The more i think of this even though these guys have pointed out some flaws in my set-up I have set this car up very similar to my Kyosho GT and OFNA DM1. Those cars hook up and this one doesn't. You have really got me wondering if there is a mechanical problem in the rear-end. hrmmm
After racing Friday night making some of the changes here like standing up the shocks, adding droop, swapping tires I had no improvement.
Will report back after Friday night.
