The rear vents are finished so I cut out both L & R front fender vents today. At lunch a few weeks ago John Horsman said that I should add one more vent slot in top of the front fenders, the existing ones were too far to the rear. I followed his advice since he has spent a lot of time in the MIRA (Motor Industry Research Association) testing Ford GT40s, Porsche 917s, and Mirages (the Gulf Racing Mirages), and others.
To make another vent, I used a 1 1/2” hole saw and the HF body saw to make a slot in front of the forward most louver. This should make the anti-lift aerodynamics more effective.
