March 2, 2012 - With the car off the dyno, I took advantage of the fact that I was at the FM shop to hijack a lift.
Step one was to clean up the front aerodynamics a bit. Previously, there was nothing between the air dam and the skid plate. I did have ducting around the radiator so that air was well used, but otherwise it was just plain messy from an airflow point of view. Not anymore!
The plate can easily be removed if I need to get in there - it's held in with a few machine screws around the bottom of the air dam and four bolts at the back. You can just see some rivets in this picture for one of three stiffening ribs that keep it from flexing, and I also did a bit of work at that corner by the wheel to add a lip for more strength. Since it's made of thin aluminum, it weighs very little. But it should do a lot to clean up the airflow.
One downside is that the airdam is no longer flexible - and the car is also much lower than it was at the Targa. So it's going to be more prone to damage. I'll have to behave myself over drops from now on.
