Yep, Lee is correct (
) the new car is slighly different, each shim now is one hole "more" than the anti-squat it delivers on the new "X6 Sq" car, ie 4 holes is now 3 degree, 3 holes is now 2 degree, no shim is in fact now 4 degrees.
We have contemplated changing the markings but that would then cause confusion in whether you have a "new" shim or "old" shim, so we have kept the current batch the same for this reason alone.
