Just installed some GarageStar super low seat rails on my FD, and made a quick vid of it.

They're sweet.

 

Make a vid that shows how the slide feature works!

 

Thanks for the vid. I'm convinced now.

 

Hey! That's not Dominic Turetto!

What's he doin' with his car?!

 

Dunno. Found it abandoned in a random indoor parking garage. Mine now.

 

Noice! Like the vid. Dude's got personality, don't see much anger

 

Wait a sec. These ACTUALLY slide? I thought that was just a joke.

From the website:
"The seat rail and all hardware is made from stainless steel and includes nylon spacers to enable you to effortlessly slide your seat forward and back using the quick adjustment levers. Nylon spacers provide a frictionless mating surface between the seat rail and the seats. Not only does this ease movement, it insures that the seat rails will not scratch or mar your carbon fiber or Kevlar seats."

SO YEAH! Let's see a vid of THAT!

 

Yeah, it looks like maybe you lift the L-shaped aluminum pieces at the rear seat mounting locations and the rear of the seat lifts and you can move it to another notch.

But, I am must speculating from what I can see in the pics and how I could reason out the sliding mechanism might work.
