The truck is as slammed as far as I can take it without removing the inner fenders (they're already heavily modified - so much that I had to modify the clutch pedal), and the back needs a little rake for down force on the bed cover - maybe more than we have? At this point, we can't go lower without removing the crossmember under the front of the oil pan, which I'd be afraid would open the oil pan to hitting the course more than it already can.
I can deflect more air over the cab by stretching the hood scoop to the absolute legal height limit of 8", and extend it closer to the windshield. That's the only allowable aero advantage we can take in production class. I was able to mount wind tells on the hood scoop opening to see that air is in fact entering the scoop at the windshield. Probably too much. I will restrict the hood opening at the air cleaner to prevent more air from entering the engine bay. I cannot push air from the radiator out the hole in the hood, as that's considered "venting" - illegal in production class for aero reasons. Picture a late model Lotus to see how beneficial it could be.
We have tight steering at 110, so I think front downforce is ample. We are VERY close to 50/50 weight distribution. Maybe even a little rear biased at this point. That's the next step before disassembly - back on the corner scales.
