I have a Raburn swing arm car with the long pull bar. I had been using a panhard bar mounted from the right frame rail to the left side of the axle tube. I have changed to a J-Bar mounted on the left side of the frame to the rear end yolk. Should this give me more side and forward bite? What does it do to entry? Can I run the J-Bar from right side frame to the yolk? If so will it work the same as the Panhard bar? WHEEL SPACER: We had been spacing the left rear to help entry. It seemed to tighten the entry. We used the spacer on the right rear and the car had more forward bite. Is it correct that spacing the L.R. will tighten entry and loosen exit, while spacing the R.R will loosen entry and tighten exit? Another question is this. When we spaced the R.R. the car had more forward bite. Does this put more weight on the right rear and if so, shouldn't I be able to do the same by increasing the R.R spring rate? If we do put a heavier spring on the R.R. we seem to have a problem with the car not rolling over, especially when the track is slick and momentum is slow. Thanks.

go24 or 2nd2none should be better able to answer your questions.
the wheel spacer on the right side, softens the wheel rate because the distance from the spring to the tire contact patch becomes longer, applying more leverage.
