After the success at Zandvoort, Rindt gained confidence in the new Lotus 72, describing it as "the best racing car that exists at the moment". But he continued to have problems. During practice for the , Rindt opted to drop his new all-enveloping Bell-Star crash helmet, finding it too hot. He went back to using his open-front helmet, only to be hit in the face by a stone from another car, causing a deep cut on his right cheek. He also suffered a steering failure on his car. Furious over yet another mechanical problem, he stormed into the Lotus garage and yelled at Colin Chapman: "If this happens again and I survive, I will kill all of you!" Rindt was still able to win the race, taking the lead in the championship. The next race was the at Brands Hatch. Jacky Ickx established an early lead ahead of Brabham and Rindt, but when Ickx's transmission failed, Rindt seized the opportunity to pass Brabham for the lead. Brabham was then able to regain the top spot on lap 69 as Rindt missed a gear and looked the certain winner, only to repeat his misfortune of Monaco: on the last lap, he ran out of fuel, allowing Rindt to take his third win in a row. His victory was cast into doubt shortly after the race when Chief Scrutineer Cecil Mitchell found the rear aerofoil not at the regulated height. Rindt was provisionally disqualified, only to be reinstated as winner after three hours of deliberation.
