Duc,
The only right side nets that I have seen recommended are the strap ones. Mine has some sort of non stretch kevlar stuff that is supposed to not stretch or something. I was used in the C5R LeMans vettes and this one is just smaller. Figures that was a smart idea...

The net has a quick release at the mount which makes it easy to "dump" in you needed a speedy passenger side exit.

No idea and no affiliation... pretty sure I dropped cash here:
