I can report that at 140 my car is steady as a rock.
I did not turn the radiator upside down; I did flip the top radiator bracket around, and I added a section to make each hose longer to compensate for the extension. This effectively angled the center radiator forward. I put a piece of sheet metal behind the radiator to "chimney" the air through the top vents. I also sealed off the bottom of the bumper, forcing all of the air over the hood. The 986 rubber radiator-to-bumper seal would not work with my GT3 front bumper no matter whatI tried so i just left it out. All of the air isn't going through the radiator, but it's certainly going through the top vents. Cooling is fine, and the nose is pressed to the pavement.
