Sounds like a nice manual setup you have there!
have you done any mods to the engine? Be careful blocking the grill as the ir intake is behind the lhs light, and the stock fan sucks air through the rad-block the grill and you'd reduce that.
Have a look at the alpina 'cow catcher' front lip for the basic idea of an air dam for an e30

Not really. A long time ago I installed a K&N air filter and that's basically it, in terms of directing impacting the engine. OH, I also have a thermostat that runs warmer than stock.
I also took out the those plastic pieces behind headlights to let more cool/cold air into the engine bay/air intake to get more grunt out of the engine. I've heard warm air is better for mpgs so I've recently (yesterday reinstalled those pieces.
As far as the air damn, that's definitely an interesting idea on how to take it. As far as covering up the bottom of the car front to back, that might be tricky, but I'll definitely take a look at it.
