Unfortunately the list of things that can cause this is VERY long and the best method would probably be to hand someone else your car to double check all the stupid stuff we all do once in a while:

* Things like shimming roll center on one side but not the other (have done it).

* Having droop screws bottomed out on chassis, often times after changing roll center (we've probably all done this, but did you catch it within the first minute or two?).

* Unequal camber (like when you whack a board, can't figure out why ride height is uneaqual, then realize your crash messed up camber on one wheel (done this one also)..

Some of the lesser stupid things:
bent A-arm pin
Crushed (uneven) spring


the list goes on.... (this could be more fun than the "Uses for Paragon" thread.)

Even when the car is perfectly balanced F/R and L/R.

I'm not using the steel lipo tray...and it could just be that since the BL motors are almost 40g heavier than brushed motors, and motors are offset to the rear left, so more weight is on the left rear side, and that could cause the rear left dip...maybe the Lipo tray would help in this regard in counter balancing the heavier 190g Novak motor, since it would a little more weight across the right front quadrant of the chassis?!?...

So to measure droop, ride height, etc, this could throw things off and cause subtle handling pblms
