I had my first race with my m-05 yesterday I did ok but not great. My shocks are to long they are the cva's not the mini cva's. What's the general opinion on adding weight? The top place finishers had very heavy cars. We are running on carpet with stock motors and open rubber mini size tires. I placed an order for proper shocks, do you think they'll be enough to help stop my inside tire from unloading so much. Or should I pack it full of lead.
