Stolz finished third in the second of the two races at the Dutch venue on Sunday, holding off two-time champion Wittmann by just 0.249s in a tense battle.
The AMG works driver was running behind Wittmann in the first stint but jumped his fellow German by pitting a lap later. Stolz's HRT crew serviced his Mercedes-AMG GT3 in 7.9s compared to the 9.3s it took for DTM newcomer Project 1 to change all four tyres on Wittmann’s M4 GT3.
