Your rs is already lowered factory
If you lower your car more than that where I live, you're gonna have a bad time.
My car is stock and I still drag that front thingy all the time.
In my own (gravel) driveway.
In and out of business driveways, etc.
Lord knows what my car would have looked like had it been lowered when I hit the curb divider that broke my wheel.
I like the looks of ground effects.
Funny thing that if I got them, I could no longer enjoy driving my car.
I wanted to put smaller wheels on my car because it takes less power to turn a smaller wheel, spins up quicker with more torque. That was my line of thinking anyways. Just to play around. Never did it because I started worrying about that scraping thing.
