When you get your TA06 up and running, get with me. I have some adjustments for you to make. The reason I don't use anti-roll bars (I call them Swaybars - "anti-roll bars" takes a bit longer to type
), especially with CS chassis is, there is a set up that requires about 8 to 10 degrees caster, in conjunction with some negative camber, in the front wheels, to allow it to control the front end of the CS chassis better. With anti-roll bars, they eliminate the "sway" that that adjustment puts into the chassis. One can see this, when going from full lock to full lock of steering, The chassis will sway down, on the opposite side of the direction it is turning.
So, if you turn left, the right side of the chassis will drop, just a tiny bit, and conversely, turning right will cause the left side to drop. Anti-roll bars fight this effect, and will cause the steering to act as though that adjustment wasn't even there. A certain amount of flex is also a good thing in a CS drift chassis. Flex does a couple of things - if that adjustment is made to the steering, the flex allows the chassis to move with it, enhancing steering. Flex also works to allow the chassis to absorb irregularities in the road surface, so drifts are smoother.
Now, you don't want the chassis to flex like a limp noodle, but you don't want it stiff as a corpse, either. Just a little flex is sufficient. You can check this laterally, by lightly twisting the chassis by hand. if there is a little bit, just leave it.
