The roofracks are off...I usually take them off as soon as I'm hauling whatever I'm hauling. Noisy, draggy and theftable.
I'm trying to decide if the mudflaps could be used to attach fairings behind the wheels. They have a pretty anti-aerodynamic shape, though, concave on the front to grab the air.
The thing on the hood produces a big airflow separation, and kicks the airflow up, reducing snow, etc. on the windshield, but it also makes a big reverse flow covering most of the hood. It's a winter-only item.
I was hoping there would be some easy rule of thumb when it came to airflow in/out of the wheel wells. I guess when I get some other stuff done maybe I'll have to try some A-B-A trials.
