I am having a new car built by a local builder. He has the rear trailing arms 2" shorter on the left. The rear end is square to the car he welded the chassis mounts 2" different and said it would help with turning. Any input has anyone tried this?

Is the car a 3 link or 4 bar ? I see in subject sez 3 link. I race vintage late model 3 link. I run my left bar 3" shorter. I.E.=left frame mount 3" farther back than right mount. I do it with what is referred to as a plug. I.E.= moves left frame mount back 3" but allows you to put it back even with right if needed. Some rules state same length bars on both sides, some don"t. The shorter left bar gives you a quicker reaction time. Hikes faster. Rear steer comes in quicker. So what my rambling is saying is yes it"s a good thing. I run my left bar at 25*/ 18 3/4".
right bar 1*/ 21 3/4". I also run 3/4" trail in right rear. Hope this answers your ? =#01h

When dealing with 3 bars instead of four even if a Z link to hike the left or on the right to ballance out the traction with out the extra steer that it adds, it too presents its own set of functions to deal with verses a more ballanced set up! I trade out in pounds of weight applied with drive angles of thrust angle pounds under throttle to add right drive to push the car left off the corner as roll out on the rear is designed to do! If you have and hold a good cross weight to hold left rear planted then you only need to add pounds to the right rear to have a ballanced weight when rolled less to be able to drive the car with roll out working and not heating your right rear tire in the process or being loose by it having less weight from hiking and adding more left drive when wanting to go left by pushing with the right with little roll out even needed! Thus this would depend on who's set up you were using in the first place! My three link runs a closed 3/8" rear and only a 1/2" of roll out with right drive in place instead of hiking to win and with out transitions with only 4 degrees on the left bar and 6 on the right of equal long lengths to deal with! It rolls very little but the pounds change by other means to plant and hook while steering left instead of pushing right with left drive!
