Doing a quick rough calculation (truck and trailer loaded with gear) on the diffuser from the rear axle to the end of the belly pan on Dark Aero:
Length: 8'
Measurement from ground to beginning of rear axle diffuser: 6.5"
Measurement from ground to Dark Aero belly pan end 10.5"
Net difference: 4"
Diffuser angle: 2.39 degrees
