Thomas Biagi endured a frustrating weekend in the International Superstars Series' first visit to the United Kingdom.

Biagi arrived at Donington Park as the standings leader, but a disappointing qualifying performance combined with maximum success ballast and contact with rivals saw the Team BMW Italia driver leave with only a few points and drop to third in the points.

After qualifying back in seventh place, Race 1 saw Biagi cross the finish line in the same position despite carrying the maximum 60kg of success ballast.

In Race 2 he got himself as high as fourth place but a series of clashes with rivals saw him drop to ninth in the closing stages.

“I am really sorry for losing a precious fourth place due to an excess of aggression of some rivals that, if not sanctioned, risks to progressively change the championship in an anti-sportive event,” said Biagi.

“Despite the 60kg sportive ballast on board, in race one I managed to limit damages with the seventh place; it is crystal clear anyway that the less powerful a car is the higher the effect is of the handicap weight therefore the M3 BMW is the most penalised car by this mechanism.

“The only positive aspect of this weekend is perhaps the fact that the results obtained today will give me no ballast for next round in Misano.”
