off topic, but people changing their mirrors and trunk lids are changing the aerodynamic coeff. as well. wonder why the draft angle on the e92 trunk lids are much smoother than e46's? they located the turbulence trips at a different location; hence there are larger gaps between the rear glass and the forward portion of the trunk lid on the 92's than 46's. they are intentional, not relaxed tolerances. remember the little dots on the tops of the mirrors of e36's, they changed those trips as gaps between the colored fwd portion of the mirror and the black plastic part.
every design element has a purpose, leave it alone.
