About BMW Z4 E89 Step 1Toe-In / Out setup

[LazyBug]

I get very confuse when trying to setup the toe-in / out for the car so hope to get some explanation here ... pls have a look the 1st picture below -->

All minimum toe's result: If i " - " both front & rear toe to minimum value then front toe i get 0.5 & rear toe i get -0.23

All maximum toe's result: Now If i " + " both front & rear toe to maximum value then i get front 0.09 (smaller value compare to 1st picture) & rear 0.28 (bigger value compare to 1st picture) ??

So whats the deal here ?? How come one increase another one decrease ?? Also the front tyre dont seen to have negative value so is that mean Toe-Out is not available for front tyre ??

Thanks for the concern.

As Andrey Varlamov pointed out, your values of rear toe are backwards to what is standard (not saying they are bad, as it all comes down to driving style and car specifics, but just "standard")

Before this i say "FWD should has Toe-Out (Front) / Toe-In (Rear) while RWD should has Toe-in (Front) / Toe-Out (Rear)" & if my rear toe values should backward then it become "FWD should has Toe-Out (Front) / Toe-Out (Rear) while RWD should has Toe-in (Front) / Toe-In (Rear)" ??
