James Pickford and the QM Engineering team missed rounds three and four of the Porsche Carrera Cup GB at Rockingham this weekend (21/22 April) after sponsorship funds failed to arrive."We're working hard to see if we can resolve the situation and get out again," said Pickford. "I completely rely on the input from sponsors for my career."Although the team was present throughout the weekend, the car did not run after Friday's test sessions. "We're committed to continuing in the Carrera Cup and we're now seeking backing for the rest of the season," said Gary Blackham of QM Engineering.
