Hawkins would continue the strong showing again in third, with local driver Vittoria Piria in fourth but only three-hundredths quicker than Visser – the top five covered by less than four-tenths of a second.
Halfway through the session, Fabienne Wohlwend – one of the few drivers with circuit experience having won races at Misano in the Ferrari Challenge – skipped half a second clear.
Visser and Powell pulled alongside Wohlwend, however in Powell's attempts to push Wohlwend into giving up the place she ran out of road and made wheel-to-wheel contact with the Liechtensteiner, launching onto two wheels and coming to a rest in the gravel trap with broken front-left suspension, necessitating the deployment of the Safety Car.
Wohlwend began to search for a way past Visser, however ran wide at the final corner and lost a second on the Dutchwoman, allowing the #95 to pressure Chadwick.
At the front, Wohlwend in third dropped back in an effort to conserve the tyres on the hot Misano circuit, before settling for the final spot on the podium.
Koyama led home Piria in fourth, with Marta García sixth and Tasmin Pepper seventh in a quiet race for the pair.
Cook finished ahead of the midfield battle in eighth, with Moore ninth and reserve driver Vivien Keszthelyi scoring the final point in tenth.
