Mine are the opposite of yours. My passenger side is a bit lighter when closing than my driver side. I haven't had a need to adjust.the clamp on the driver side seems to not have as much tension as the passenger side but not I’m not sure it will be an issue and not sure it’s adjustable.
You can adjust the tension if need be. Lower your sun visors. On each side you'll see 2 felt pads stuck to 2 bolts. These bolts are attached to where the Sunrider clamps grab onto. Remove the felt pads (they can be re-used, so don't lose them) and very slowly loosen the 2 bolts just enough to get some movement. A little goes a long way here, so don't go crazy loosening the bolts. Adjust forward or back to increase/decrease tension as needed. Tighten the bolts back up, replace the felt pads and you're good to go.
Again, I didn't actually do this myself. Leave things as is for now. If you have no leaks and the top latches without issue over time, there's no need to do anything. If you feel the top has stretched a a bit and the clamp/s have become loser, then adjust as necessary.
Enjoy your new Sunrider!!!!
