Joe Osborne’s first win as a McLaren Automotive Factory Driver was the headline in what turned into one of the most successful weekends in McLaren’s British GT Championship history, the 570S GT4 scoring both class wins and podiums at Snetterton. In the first race on Sunday morning, Osborne led home a one-two finish for customer Tolman Motorsport and the McLaren 570S GT4. Osborne’s car, which he shares with David Pattison, started the race sixteenth but quickly climbed the order to tenth before the safety car was called into action just a handful of minutes before the pit window opened. With the field bunched up, and the opportunity to pit coming under safety car, almost the entire field came in including Pattison, who handed over to Osborne.
