Curt also recommends a stabilizer strap. I am not at all happy about the idea:attaching a clip to the edge of the trunk lid; but it makes sense.
I was hoping for report like that. I will take 1 bike from Dayton OH to Gaylord MI (7 hours of mostly interstate highway) later this month.Have been transporting 2 fairly light bikes (40 lbs plus Yakima rack at around 40 lbs) with no problems whatsoever.
Thank you. I would rather feel that I don't need to use this strap. I have an Allen Sports S525 two bike carrier hitch rack. In combination with the bike, they total about 60 lbs onto the hitch, or 30% of capacity, using your math.The Curt strap secured to the trunk -- with loads from 56-80 lbs or 28-40 % of capacity -- seems rediculous!
