I think everyone is aware of this, although the above comparison of the "off-the-shelf" PSS is being made with the "off-the-shelf" PS2. Although I'm sure the PSS has better outright performance than the BMW PS2, there is no hard data or a credible review to suggest how much better an "off-the-shelf" PSS is over the BMW PS2. It's a shame that BMW don't have a homologated version of the PSS for the M3.
