There are people who will tell you that it is essential to make the car as stiff as you possibly can. I am not one of them.
If you feel like you have too much body roll in corners then you should maybe look into stiffer bars. Otherwise, leave it alone.
I will speak automotive heresy here and say that I can control my NA better than my RL because it has a more compliant suspension.
Our roads are not glass-smooth, and stiffer suspensions tend to bounce around, reducing control.
Do you have DDM's ProBeam? If you don't and want to make a step-change in handling, get one of those.
