Am I missing something? There's a box (what's it for?) on the right side of the car, but on the left, I've got this bracket that doesn't seem to be connected to anything. Any ideas?

 

the "box" is the EVAP unit, and it's part of the emissions/gas recirculation system. The picture you show almost looks like an anchor for a tow hook in the event you had to pull the car onto a flatbed from the rear of the car.

 

You cant put the car on a flat bed rear first, it will scrape the front....

 

Mine sits FAR lower than stock... it can get on one FINE without scraping.

I call that hook the, "f me up hook"... I've hit my head on it several times when up on the lift.

 

it looks like a tow hook to me. dunno what else it could be

 

Wouldn't a tow hook be dead center on the car?

And thanks for the pic. That is a great place to stick the hook of my bungie cord when I need to transport items that don't allow me to close my hood all the way!

I used to use the tailpipe hangers.

 

Tow hook, normally if they put it on the sides, they will put one on each side. It is in the center in the front, so just tow the car in the front and strap it down in the rear with that hook if there is only one in the rear.

 

So what's the screw for? Is that there the underbody diffuser mounts or something?

 

daaaa! it's a mystery

 

Perhaps is is for the tie down on ship when coming oversees.
Makes sense to design a quick release point while designing the car. Less chance of screw up by the shipper.

Who really knows for sure?

 

I've always thought that those were the hooks they used to tie the car down while in transport.

 

It's a tie down used while shipping. Take it off, I did, save a few pounds of dead weight.

 

Ahh.. the crew IS for the Aero diffusers:
