I recently heard about the BMW Performance range, a collection of official aftermarket bits and pieces that can be retro fitted to sir’s 135i. Given a few of the photos below are taken with parts fitted to an M3, it seems as though it shouldn’t be too long before BMW offers the parts across their range. In the meantime, more pics and the official BMW press release are included below. It’s a bit boy racer, but the steering wheel with shift indicator and small display for lap times seems pretty nifty.
