Those woodscrews haven't even loosened up in 2 months of driving, I'm not too concerned. Since they're self tapping they're made to stay.
Did some tests tonight, didn't feel like making my own thread about it again....
Subaru Outback Mirror Delete Results
This was done the sameway I tested the Hot Air Intake. I went to the straightest, flattest road in town and chose two markers 1 mile apart from each other, set cruise at 45 mph, reset the scangauge meter and cancelled with the brake, resuming the cruise.
Did a total of 6 runs, then changed the variable, then did another 6 runs:
Runs with Mirrors:
1: 35.8
2: 37.5
3: 37.7
4: 38.6
5: 37.2
6: 38.4
Runs Without Mirrors:
1: 38.0
2: 37.5
3: 37.6
4: 40.1
5: 40.1
6: 39.3
Runs with Average: 37.53
Runs Without Average: 38.75
over 1mpg difference at 45 mph where aero is just starting to effect the mpg seems like a signifigant loss, as I was expecting with my truck style mirrors. Its not unreasonable to expect nearly a 2mpg loss at 70+ mph with them on.
Needless to say, they're gone for the time being.
