You will cut CO2 though, if you are considering that.

Are those numbers for the '13 model? Did it change? Stuff I found was old, but only mentioned the first couple years.

I was thinking of a full skirt wrap around and drop the front to about 1" of clearance. sides 2 inch of clearance ridged but needs to be flexible if anything in the road .. i'm just wondering what everyone else uses
