Page 221 of the E70 Manual:

"Rotating Wheels between axles
BWM does not recommend moving the front
wheels to the rear or vice versa, as otherwise
the handling characteristics may be impaired."

Imo, some of that is lawyer/prod liability bs,
but even the E70 does rec'd against it.

The genius stlr should have known, but then he
didn't take the 30 secs to check tp...
