I went searching for more information on this car, trying to find if LMR ever made good on their promise to produce aeromods for the C6. It looks like they didn't, but I did find
a more in-depth article on the car and windtunnel. The captions to the pictures give the most information, including the following:
-"The first mod was to seal off openings in the grille, splitter, and fascia.... This is standard practice in top-speed competition and took a solid 18 counts off the drag coefficient."
-"LMR co-owner, Josh Ledford, crafted up some low-tech wheel discs to flush-cover the 19-inch rims, front and rear. We kinda thought this would be a big step and it was, immediately taking off 12 counts of drag while (or perhaps by) reducing overall downforce."
-"The outside mirrors were then folded in from their normal position seen here. This proved aerodynamically effective."
-"Tom Froling then suggested altering the car’s rake by lowering the nose somewhat. Rather than mess with suspension adjustments (nearly impossible with the car on the platform) the crew simply added sufficient ballast weight under the hood and in the cabin footwells to drop the nose by about 12mm. The effect was rather dramatic, lowering drag by 8 counts, and benefiting downforce to the point where the overall lift coefficient was down to 0.001."
-"By now, we were running out of time, so for one final Hail Mary it was decided to extend the baseplate of the front splitter (by about 1.5 inches at the center and tapering back towards the outer corners). By altering the car’s front/rear aero balance, this proved very effective, taking another 4 counts off drag."
End result: .373 down to .307.
I'll post this in the Crossfire thread, too, as they may be interested in it.
