It's a myth that you can just change the body roll at one end of the car. That would be true if the chassis were made of thin plastic. The chassis is typically about 10x stiffer than any suspension component, regarding roll. Adding a big bar in the back will reduce the car's body roll, but also increase oversteer, and make the back end come around very easily.

It's not a myth. .. it's just varying in how much it'll affect your particular car based off of set up. A stiffer bar in my case should take a little away from the aggressive bite I get at higher speeds.

I was assuming by roll you meant body roll. Is that true? Not trying to argue, just need to make sure we are talking about the same thing. Putting a stiffer bar in the rear will not make the chassis twist in any significant amount, except mabe convertibles.

For all set-ups, increasing the rear roll stiffness will increase the rear weight transfer bias, and increase oversteer, and decrease understeer.

From the pic looks like your a hard core driffter. Based on competitions I've seen on TV, looks like it takes increadible talent, and accuracy.
