rear anti rollbar

Hey guys, I have a question about the use of the rear anti rollbar,and what your experience are with this set up tool.
We are circle track racers from the netherlands and racing on short ovals about 1/4 mile asphalt or less. In Europe the use of a rear a.r.b. is very populair on asphalt,(not on dirt)and have some discussions with other chassis builders of our class. I follow the way of thinking from Bob Bolles , and I think he,s right when the cars get into the corner ,the a.r.b. lift the L.R and use that weight for less roll. Over here the say that the use of the a.r.b. hold more weight on the L.R.
With the use of a rear a.r.b. you can run with a lower rear R.C. and have more vertical loading on the R.R. for more exit speed. I must say that the cars must run on the same tires on every corner,and the use of an L.S.D is permitted.
Weight : 625 kg to 687kg  50% front rear   52,5 inside most guys  light building chassis 55% inside.

The use of anti roll bars (sway bars) in the rear increases the rear roll stiffness without increasing the spring rates. This way you can use the springs to control nose dive and squat without affecting the cornering. You can achieve the same effect as with a sway bar by reducing cross weight
