I've done some more digging over the last few days. Thanks for being a member who at least replied Aero!
I've got some ideas going right now. I had off today, but a friend is moving from Pennsylvania to Alabama. That has kinda taken a bit of demand to spend free time with my buddy before he leaves.
Maybe I can get some sketches done up.
I do have a first generation prototype made for some front bumper air deflectors. I'm hoping I can tie in a lower air damn to meet these in the same location in front of the tires.
My current goal for the Subie are as follows:
1) Front bumper grill block, lower eurothane bumper portion does limited value to cooling and has been proving useless by a fellow Outback owner.
2) Side mounted air deflectors to move air off of the front tires. Factory tires stick out past the front bumper. It basically drives front air into the tire tread area. Simple fiberglass machup has been made to move air past the tread and at least partially past sidewall. These don't increase frontal area, but redirect air outward
3) lower air damn. Hoping to make a wide-skinny-wide with a curved radial shape. W-S-W meaning Tall-Short-Tall. I'm looking to deflect air off the undercarrage and off the lower suspension/tires. Again minimizing frontal surface area increase, while deflect air away from areas that make turbulence, while keeping most/all of the ride height (hence skinny in the middle). Hoping to get this sized into and matched with the air deflectors from #2
4) form cone shape aero parts to direct air around factory subaru mirrors. They are monsters on the 2000-2004 Legacy/Outback. Hoping conical shape will provide better air flow around the mirror which is current a round edge, blunt rectangle.
