Help ID part please

[tristangoesham]

I found this in the grass area between my car and my neighbor's car. I'm not even sure if it's mine or his. He isn't home right now so I was wondering if someone could ID if this came off my LS. Looks like it could be part of the suspension or something.

Doesn't look like anything I can think of on an LS.

What kind of car does your neighbor have?
