Rear
I'll have to do something about that lip. The rear section is fine but the transition to the fuel tank is a step. And the RH side needs some kind of cover, it's acting as a scoop.
Preliminary testing (i.e. I couldn't wait and wanted a number) indicates 6.5-7.5l/100km for the short flat sections we have around warwick, and it seems a little quieter. So it's *slightly* better than last time I went on a trip. However more to the point, nothing fell off at 130...
