The seat legs on the sub frame touching the floor has tall legs that can be CUT. Meaning they can be cut in the rear and the angle of the legs as it lowers will allow you to bolt them back together after drilling two holes in each leg that will let you install a nut and bolt. Make sure to get automotive grade 8 bolts and nylon nuts to keep safety.
You can do this to the front legs too but found only the rear legs needed done. This gave the lower seat section a nicer slant.
The only trade off: Less foot room to the rear occupants.
Not too bad on rear leg room in my opinion.
