If the front and rear diffusers aren't making more downforce, that will cut drag. The old flat-bottomed cars at LM in the early '80s were competitive because of not having the same drag as the tunnel cars like the Porsche 956.
And the louvers ad fairly little drag, in spite of Audi and Peugeot's rabid attempts to reduce having to use them (and their liability to get damaged in races, which with the ACO is basically a no-no), especially with what the early Audi R15 used at Sebring in '09 with a full set of flush fitting louvers.
They do add downforce and drag, and reduce lift, but it's marginal compared to wing angles and diveplanes, which we have to question that with the huge diveplanes that the Audi R18 ran at LM this year, even running a twin HD set in practice.
