With the bikes low like that, what % mileage loss do you see?
I considered the stealth hitch, but with the bike rack installed, I could picture the bottom of the rack tongue extension hitting the pavement when making a sudden transition on a short steep driveway. That looks that is a possibility from your photos. I did get the invisi-hitch and use a Yakima rack. Yes, there is significant aero drag with the bikes hanging high. CD range goes from 40 miles down to about 26 when driving at 65 mph. I'm taking the rack to welding shop to have them cut off about 15" off the rack vertical post to get the bikes back down behind the car. I may take the (bike) wheels off, too, on long trips. They add a lot of drag by themselves.
