My top is fine at highway speed. Yea I wish it went all the way back but the whole top being exposed is all that matters. Never has the top flopped at speed when folded back its to heavy it move.
It's actually good you got the hard top. If you get the soft top and then go to a hard top you have to get the hardtop electrical hook up kit for the rear wiper and lights. So your already ahead of the game.
You should write up a instruction manual on how to do it and sell copies for 10 bucks a piece. But great idea those rear belts drive me insane whipping around.
I don't think once it says in production you can't make changes. But if you want one tell your dealer when time gets closer and have them order you one or buy a nicer aftermarket one.
