Following the 1986 race, and as part of safety upgrades the circuit needed to bring it up to FIA standards for inclusion in the 1987 World Touring Car Championship, a chicane was added to Conrod Straight, eliminating the second hump which had long been seen as dangerous at the speeds the touring cars were traveling (the V12 Jaguar XJS of Tom Walkinshaw was timed at a then fastest ever 290 kmph on the straight during qualifying for the 1984 race).
