i received mine a few days ago :-)
i already have three other bmw cars equipped with kw clubsports and am pretty happy with them.
it is the same hardware as fitted to the gts and crt cars... although the clubsport is a little more hardcore concerning the setup.
more pics of the M3 kw clubsport here:

i hope i'll find time to install it soon!
