Masta Kink The Masta Kink "was by far the most difficult corner in the world", according to Jackie Stewart, requiring skill and bravery in equal measure to get it right. After a long run from Malmedy, the cars would reach top speed before having to negotiate Masta, a high speed left-right chicane, and a good exit speed was vital as it was followed by another long straight run to Stavelot. This was a very fast and very dangerous corner, as it was situated right in the middle of two long unbroken straights, both about long. The speed in this sector could reach . Masta was removed from F1 racing after the 1970 season. Jackie Stewart's crusade to improve safety in racing was set in motion by his crash there in 1966, when his BRM ended upside-down in a ditch near a farmhouse on the outside of the corner, with fuel gushing out of the tank onto Stewart, who had broken ribs. At this point, many of the Formula One drivers disliked Spa (including Stewart and Jim Clark, who had some of his greatest wins there) because of the immense speeds that were constant on the track. While he was spectating at the 1972 12 Hours of Sebring, Stewart attempted to organise a boycott of the Spa 1000 km race that year, a move that was not respected by many of the drivers, because Spa was still popular with racing drivers outside of Formula One. Stewart later described the old Spa circuit in 1986 as being as "ferocious as a tiger", and he later described Masta in an interview in 2011 as perhaps the hardest corner on any racetrack he raced on in his career; even more so than Eau Rouge. Another particularly gruesome story comes from the 1972 24-hour touring car race. During one of his pit stops at night, Hans-Joachim Stuck shouted to his co-driver Jochen Mass over the noise from the cars that he should "look out for body parts at the Masta Kink". Mass arrived there expecting to see pieces from cars all over the road but was appalled to discover it was in fact the remains of a marshal. After Masta, and at the end of the subsequent Hollowell Straight, there used to be a sharp hairpin at the entrance to the town itself, which was later bypassed by a quicker, banked right hand corner.
