Whiting was born on 12 August 1952 in Sevenoaks, Kent. He watched his first motor race when he climbed over the fence to see the 1964 British Grand Prix, held at Brands Hatch close to his family home. He came to working in motor racing himself through his older brother Nick, who was competing in autocross and circuit racing. Having decided to follow a career in race engineering, he attended a technical college and then the Borough Polytechnic Institute, earning qualifications in mechanical engineering.
