With a newfound interest in improving the car (due to the demonstrated efficacy of throttle stop testing), I think I will be putting time into undertray cleanup.

While the car is generally pretty flat underneath, there still appears to be a lot that could be done to smooth flow up front, around the suspension, and the huge triangular gap under the motor area. (The heat exchangers are in the front and only the heat of the range extender exhaust system seems like a legitimate concern.) I honestly think BMW was just being cheap on all counts.

I'd really like to get some professional looking rear skirts done (not down with the coroplast look), but I think the undertray work will be a more productive and easier area to work on.
