This is a variation of the same theme from Road Atlanta.  Minor difference being the addition of dive plans and end plates outboard.  It is difficult to see in this picture, but the front splitter is slightly anhedral.  That is, the middle segment is higher from the ground than the outer segment.  This reduces the pitch sensitivity of the front end aerodynamics making the splitter less sensitive to stalling and choking the underbody (also known as porposing) in low ground clearance situations.
