Did you build this?
Would you be willing to share your design?

You can do as you wish. I never even made a formal drawing, just measured and cut as I went as I was in a hurry. If I have time I could measure and make a parts list. Its pretty self explanatory from the pics. The idea is to support the seat base over the widest area practically possible, while connecting the subframe halves together for strength and not impeding airflow. If you have access to a mill, or even patience with a saw, you could make the entire frame from one piece of alloy plate. I did it all by hand from bar and angle stock.

Thanks for the response. No need to get dimensions. It is all pretty simple.

My only question is what did you use for the seat supports?
I drew some arrow to the parts that I am not quite sure what you used.

Looks like plumbing caps over nylon post.

Yes, they are poly tubing caps over 1" sections of thk wall nylon 66 tubing. All stock off the shelf from McMaster. Been busy with house project, I'll lost more details later. My buddy is picking up his '12 next seek so we will make another.

Nylon 66 spacer, 1" H x 1" W x .5" ID, Mcmaster # 94639A880 $11.94 /25

Polyethelene pipe cap, 1", Mcmaster # 9567K14, $7.58 / 100

These are retained by an M6 bolt, nut, washer, and a short piece of rubber fuel line that expands when the bolt is tightened. The idea of the cap is to allow fine adjustment of the height with washers between the cap and spacer. You want the seat base to just contact the cap. You can see this by looking from the side. I also added a short M6 screw, nut as a locknut, and .5" cap to the top of the coupler nut that retains the brace or original batt box. This is also adjusted to just contact the side of the seat base. The idea is to provide support to the sides of the seat, preventing that flex and rolling feeling when you shift your weight to the side.

The result is a 100% improvement and elimination of that cheap feel to the seat.

If you have access to a shop there are many ways to do this. These parts allow a quick off the shelf solution.

Neat stuff...I looked for fun to see shipping cost...LOL 89.20 Euro's...LOL No thank you
