Sl0eg1n's xray is one of the most balanced cars I've seen. Most people would think that the side with the batteries would be the heavier side. We stuck it on a balance and the battery side was lighter! He had to stick 10 grams on the battery side to balance her out.
As far as body roll. That's all shock/spring combo as well as setup. D/L a setup for your TC4 from one of the drivers list. Sl0eg1n is running a stock setup, I think and it does push a little bit.
The TC4 has an inhereant push as well, even when setup correctly. You will have to take care of the shock oil and mounting as well as the spring combo. The sway bars do help.
BTW, just keep in mind that setup and tweak settings are all trial and error. Both sl0eg1n and I can spend hours setting a car up and testing (both electric and nitro). Once you find a combo that you like, it's all just a matter of minor adjustments when you go from track to track. Keep asetup sheet handy so you can always go back to a baseline setting or have your setup handy for each track and not have to play around too much during practice.
