    Or...get the weight where your car works best in the slick and the use the "crutches" to help free the car up early on when it's tacky.
    I agree. We are trying to get the car in the right state at a dynamic moment in time. The static reference doesn't mean that much. Just so that we wind up in the right place on the track.

      I would like an answer to taylor 27 27 question also, it would seem that raising on frame and pinion both would favor the rr tire more but I have yet to see any opinions yet.

        I think you have to define " sidebite" first.Some people use the term to describe a loose car,others to define a car with an over all lack of grip.

          does car scotch up on entry through middle in slick?
          Does it feel like car is tripping onto RR tire and it is forcing it into track? being able to stay, or get back to throttle and car drive straight off corner?

          OR

          does it feel like car slides on entry,( depending on how driver enters corner) and through center, and you have to wait to get back on throttle?
          I think there should be lifeguards in the genepool.

            Raising both ends of the j-bar will reduce lateral transfer by raising the roll center, thus typically loosening entry

              We've tested raising the j-bar on both ends.It loosen the car in what we call the transition zone,Most people would call that late entry or early apex zone.Maybe just different wording between teams.Reducing lateral transfer, I can't agree with that ,but until I have data acquisition I can't ague it either.

                CoG and RC. Find the points. Make a line. That line is your "moment arm". Longer it is, the more weight transfers under a lateral force of X. It's that simple.

                  Like grt74 said we very rarely move our jbar either, its just another crutch.(but one alot of people rely on) and yes moving the j-bar to far down will hurt you bad..

                    If I can remember correctly, Rocket suggests starting the J-Bar on the frame at 8.25". By feature time, on a wide-slick track, how far will teams raise the frame height of the J-Bar?

                      Rocket actually wants 8 3/4" bottom of frame rail to center of bolt. My guys and pretty much everybody else I talk to are at 9 1/4"
