The Dutchman was probably still feeling put out at having to give up pole for Race 1 after a problem with a tyre forced him to start from the back of the field.
This time he bossed the rest of the pack, starting from a surprising second placed Ardagna Perez (1:41.242). Right from free practice the Venezuelan has appeared at home on this track and limited the gap to Pastorelli to just a second.
Tucked in behind him after a superb showing is the Belgian singer Kris Wauters, who edged out Peter Sundberg - the winner of Race 2 at Monza. Wauters made up for making the wrong choice of tyre in session one and his third place is a brilliant springboard for his target of a podium finish.
A puncture led to Sundberg spinning ten minutes from the end. For the Swede, who could have troubled Ardagna Perez as much as he did in free practice, the damage was limited by the rain that began to fall just two minutes later. The placings were frozen from the time the rain started coming down.
Behind Sundberg on row three are Paolo Necchi and Marco Petrini. The quickest GT4 driver, Jonathan Sicart, and Emanuele Smurra are up next. The winner of the first ever Trofeo series still has to fulfil his potential in this championship and was looking at this qualifying session as the turning point in his season. The rain put paid to this plan and the Roman driver was not alone in feeling hard done by as La Mazza, Segler, Hommerson and Frazza, occupying positions nine to twelfth, were also affected.
The Dutchman, at Zolder as a guest, clocked the best time (1:40.769) but will start from the back of the field because he will have to change tyres after damaging one.
So, Niek Hommerson, who had posted the second best time of 1:42.010, will start ahead of a Pietro Zumerle who improved on his showing in free practice.
Nicolò Piancastelli (1:42.240) and Roberto Sperati (1:42.329) will be on row two; both put in great performances. Apart from Pastorelli, ten drivers are within a second of each other.
After an encouraging free practice session, Paolo Necchi had to be content with fifth, alongside Kris Wauters. Seventh on the grid is Steven Goldstein, just 35 thousandths up on Enrico Moncada. However, the driver from Catania was another to be relegated to the back, just like Pastorelli, as he also needs a new set of tyres.
On row four will be Ardagna Perez and Francesco Maggi. On the fifth row will be Jonathan Sicart – the fastest of the GT4 cars – and Andreas Segler. Bringing up the rear will be Peter Kutemann, Marcel Pawlicek and, as mentioned before, Nicky Pastorelli and Enrico Moncada.
