23-9-94 s mao 10 ors: Steffi's brother revs up in Christchurch MICHAEL GRAF. ..Steffi's brother in Christchurch for the Peter Jackson series By LINDSAY KERR STEFFI Graf's brother has chosen a chequered career. Not that fussed with tennis - in which his sister is the women's world No.1 - and with little interest in the family sport, soccer, Michael Graf stumbled into motor racing. The 22-year-old, in New Zealand for the Peter Jackson international series, explains that his background is far removedfrom the racing circuits he frequents now. His grandfather was a professional soccer player and his father was also into soccer. "I never played tennis seriously, perhaps once a week," he says. "I was more interested in water sports-a few years ago. "I never liked soccer, either, and never went into motor racing, even though the Hockenheim circuit was close to our house. "That all changed when I went to a motor racing press day and I loved it. My times were OK, too, and things all went from there. "I had just finished school and wanted to be a surgeon but to do motor racing properly I could not have gone to university as well." That was three years ago and Graf is now a full-time racer. His trip to New Zealand will see him run the Reynard Formula Atlantic car, in which Kiwi Craig Baird won last year's international series. Like many of the promising prospects who do the New Zealand circuit, the chance to drive something more powerful than they've been used to is OpEL STEFFI GRAF...looking good for an Australian Open win this week. also why Graf is here. Today, be will line up in Christchurch for the Lady Wigram trophy race in the first round of the championship. The car is 50 borsepower more than he is used to. He has competed in the German Vauxhall-Lotus series and the Formula Three championship. "I should have stayed in the Vauxhall-Lotus series for another year but the team I was with were changing to Formula Three so I changed too," says. "It was a good enough season with a few fifth and sixth places in fields of 30. "I want to use this series as ideal practice to go home with the best of preparation for this year's championship. I must aim to win it. "If you don't aim for the highest level then there is no point in doing it." Like his sister, he wants to be the best in the world. "Our family is very proud of Steffi," he says.
