dfco in 3rd gear
The steepest downhill is 7 degrees, with a couple of 90 degree curves, all done dfco in 3rd gear. Now I'm quite sure my changes to the bumper and vent caused an increase in drag, and the reduction in speed / mpg. I previously had the bumper cover at 7" from the ground, slanted back, and now it is 8.75" from the ground, almost vertical.
Most of the belly of my car is 8" from the ground, 20% is 7" from the ground, and less than 3% is 6" from the ground. I should have left the bumper cover at 7", and will probably redo it to that height, but am going to work on an undertray first.
Thanks for your comments. I'm planning to change the hoses at the next opportunity.
