I plan on setting the rear up square on scales. What I'm looking for is how much should I let the left rear travel fwd when the body rolls and on the throttle?

That all depends on what the car does and what you want it to do. You don't typically "set" dynamic rollsteer to a pre-determined amount. But yes you do set the static rollsteer in the shop. A left rear 4-bar setup I designed generated 2.25" of wheelbase change from rideheight to full extension.

If you want more rollsteer raise the bars, less then lower them.

thanks njantz. I have a three link with 30" rod on the right side and a 17" on the left.
right rod is 10 deg and left is 18 deg. have 2" of change at full extension. I guess that is a good place to start.

Wilson, do you run your bars like that wet and dry, or just dry? I have the same bar length set-up this year and I'm still trying to figure it out.
