leaf spring - what if

[geometryjeff]

OK guys - correct me if I'm wrong. Rear wheel steer on a leaf car is caused by the angle change of rear end housing when car body rolls in a turn; the leaf on outside (opposite direction of turn) flattens which cause the chord length to change moving that end of axle toward the rear while the opposite spring moves in opposite direction moving that side of axle towards the front - right? Rear wheel steer drives the rear of the car away from the direction of the turn for reduced traction and posible spinout. What if you could counter that movement? Would traction improve? What if the front eyes had a swivel point and the rear of the spring were controlled to allow movement to counter the rear wheel steer? Yes, there are still issues with the rear end having fixed points on the axle, but I"m just thinking about theory. If a servo or something would allow real time movement in a turn, would that create better handling coming off the turn with better traction, or would the opinion be that the car would get really squirrely and have a squishy feel? I don't have enough engineering or seat time for a best guess. There seems to be a lot of autoX'ers at this forum and I'm learning a lot from your posts. Keep up the good work for us rookies.
