It will be a very special event that will draw the Ginetta G50 at Mugello this weekend at the Sara Racing event. Mugello will host the fifth round of the reserved trophy for British GT4 cars and debuts  important as those of the former Formula 1 driver Alessandro Nannini. One more reason not to miss the show this weekend Saturday with the official practice of the Italian championship car and the Mugello Marathon. Sunday, however, will be devoted to the races.
