Yes, It adds downforce.. it's not a 'bodykit' its a front spoiler.
It's from MSA:
Front Airdam
It's hard to see cause it's black. But yes it adds downforce... without it the front end feels light on the freeway. Normally the air rushes in and press up against the inside of the hood creating lift. Giving out highspeed 'light steering' feeling. My front spoiler deflects that and helps cool my brakes a bit as well. If I ran some ducting they'd cool off better.
