BMW is in a dominant position through the first quarter of the Spa 24 Hours.
Two of the leading Porsche teams, BMS and IMSA, changed onto wets during rain showers in the fifth hour. It helped them close the gap on the BMWs, which had pulled away in the dry conditions, but as the track dried again the slick-shod M3s reasserted their advantage at the front.
The No. 79 BMW, now being driven by Dirk Adorf, currently holds a lead of just a few seconds over its sister car, which gained ground at the last pit stops.
Third is held by the No. 13 Prospeed Porsche, which also stayed on slicks during the rain and is due a stop soon. It is over two minutes behind the leaders. The No. 23 Porsche, currently being driven by Jorg Bergmeister, is fourth, and is set to regain third when Prospeed stops.
The only competitive Ferrari, the No. 2 AF Corse machine that lost time early on, is now fifth, a lap down, ahead of the No. 16 IMSA Porsche.
GT3 is still led by the No. 50 Phoenix Audi of Anthony Kumpen/Marcel Fassler/Lucas Luhr/Mike Rockenfeller, in seventh overall.
