Hey Lio thanks for helping with my seating decisions. Maybe I can help now. I ordered the 600 series base, the sliders and the side mounts. And if you put all of them on it actually sits higher than the stock seats.

So I ended up fix mounting it the the base with the side brackets. Which is no big deal since I'm the only one that ever drives it.
Now I just need someone to walk me through tricking the airbags with a resistor.
