    I don't know much about a teeter totter, guess im to old, but getting back to the original post concerning tying the left front, I still say it effects weight transfer to the right rear

      I guess you could say your wedge is your fulcrum and your teeter tottering left front to right rear

        To a point yes. The wedge is what you end up rotating around the car. Now static load is different than dynamic, if i throw a 168 grain bullet at you it might sting you more than if I drop it in your hand but if I fire it out of a rifle it hits you with over a ton of weight. First a teeter toter is another rotational movement of weight. This combined with the car turning left affects the movement of weight in a circular direction. This change in loading at the fulcrum as the car lifts, rotates and trys to send energy in a straight line is only stopped by the loading on the tire patches as we try to drive forward and turn the car. This is causing me to use classes I took 40 years ago.

          ok, you might be older than me lol, I was trying to answer the original posters question about chaining the left front, I do understand dynamic load aspects , someone stated that weight cannot transfer diagonally, I was only trying to explain that you can manipulate weight transfer from left front to right rear by adjusting shocks and using chains on left front . it hasn't been quiet 40 years for me, but I may have to go dig up a few of them ole stone tablets we used....LOL.

            This is a car that runs at a local track it's a floating X car that's running a tied down LF on a track that's notoriously slick this is as it's passing under the flag stand on the last lap. You can maybe see why there can be an aero advantage also not running crazy hike or rear steer....he won that week but that floating x car can be very moody it seemed

              that track looks very tacky, I would think that would be where the tie down would work best

                It's just the camera exposure, and we have very red clay its black! I saw pictures of a track in New York that stuff almost looked white.

                  heres my opinion or whats going on from a physics standpoint,does weight move diagonally??? the answer is no,now I can understand why some people would think so but its impossible,i could break it down but it would be 9 pages long to explain about a late model going 100mph and then slowing to 60mph,
                  it takes two movements to get the weight to the rr,the car has to fall to the rear and with the side load to the right,now in a late model this happens at a very high rate of movement,but again I can see how some would think it moves diagonally,but in a physics world its two or more movements
                  this is without getting in great detail,just trying to help some understand whats going on
                  I could explain it but you have corner entry,mid corner,exit, straightaway,but then would have to wright a 20 page article,
                  mark bush and some others have classes on this,
                  just trying to explain from a phyics standpoint and not trying to ruffle any feathers

                    What is a floating x car? I've heard this before but I've never understood.

                      It's an X brace in the chassis that's clamped and not welded solid it's supposed to allow the car the flex for it's less sensitive to changes but the problem there is it takes a huge change for a small effect. The hope is that a well built car will run in any conditions, so we can tune ourselves out the problem is they end up fatiguing and go dead over time IMO some still get them built as an add on option but most people welded them up

                        I was a crew chief on a 09 Swartz with a floating X. One of the best cars I ever worked on.

                          I forget if his is a GRT or Swartz the Swartz is very popular at Winchester, Pettyjohn is crushing them up there in one.

                                They didn't state anything about the physics we are talking about, their competition director just stated what they found that helped some only some of their clients.... They had to start out somewhere too. Debate back and forth and working through problems and wording is how things get done and people learn and pick and choose what they want to apply. If you're in the industry please for our benefit state who you're with so we don't have to support someone so condescending. You can't state "facts" that fly in the face of the Laws of Physics. If your going to try to talk condescending we might take you more seriously if you at least use correct grammar and spelling.
