Championship, while Clark won his second Drivers' title with ease, Spence could only record two more points finishes, coming fourth again in Britain and third in the season finale in Mexico, behind American duo Richie Ginther and Dan Gurney, in what would turn out to be his only podium finish in a Championship race. With ten points, he was eighth in the Drivers' Championship. The season began with victory in another non-Championship race, in South Africa. However, Lotus boss Colin Chapman then took back the recovered Arundell, leaving Spence out of a drive. Before the Championship began in May at Monaco, Spence signed for the privateer Reg Parnell Racing team, but the BRM-powered Lotus 25 he drove was elderly and unreliable and he finished only twice, in the Netherlands and Italy, although he was fifth on both occasions. The four points thus earned placed him 13th in the Drivers' Championship. At the end of 1966, Graham Hill left the works BRM team to join Lotus, and Spence was chosen as his replacement. Driving the BRM P83 over the course of the Championship, Spence achieved points finishes in five races, though these consisted of four fifths and a sixth. He thus finished tenth in the Drivers' Championship with nine points. Continuing with BRM at the start of , Spence drove the P115 in the season opener in South Africa and the P126 in the Race of Champions and the International Trophy; he retired from all three races but performed strongly in the latter two, hinting at a great potential for the rest of the season. Sports car racing In 1967, Jim Hall hired Spence as part of his Chaparral sports car team. One of the most innovative engineers in 1960s motorsport, Hall pioneered many advances in racing technology. For 1967 the great advance was the addition of aerodynamic wings to the rear of his cars, generating extra downforce to improve grip levels and hence cornering speeds. Driving the Chaparral 2F with regular partner Phil Hill, Spence managed to make a great impression on the sports car scene. Fastest laps in the 12 Hours of Sebring and 1000km Spa races were just the prelude to a dominant win in the 1967 BOAC 500 race at Brands Hatch. Spence and Hill finished half a lap ahead of the Jackie Stewart/Chris Amon Ferrari 330P, who were themselves three laps ahead of everybody else. For
