There is a point where you can have to much traction on a not so high grip track. At that point you need to use body roll to keep you from sliding. The sway bars are great for high traction carpet and totally prepared smooth asphalt none of which we are running on. The 4 alum posts for the upper deck make the chassis to stiff for a not so smooth track as well. I'm running into issues with this on my TC5. I'm having to loosen some screws on the upper deck to accomplish this. I'm also going to put shock O-rings under the upper deck to give it some play.
These little guys are temperamental. Little things mean a lot when it comes to getting the most from them or in some cases just being able to drive them at speed.
