If you're not concerned about slipstreaming the lip will still reduced lift though correct? It will not be as efficient if it doesn't meet the road and stay attached but you're still decreasing the area that the flow is not attached therefore decreasing lift.

Kind of like the 2007 STi? I can't find a good pic to post
