. On the penultimate lap, Streiff tried to overtake his team-mate for second place with almost disastrous results as the two cars collided. As a result, Streiff's front wheel axle was severely damaged. While Laffite carried on in second, Streiff managed to limp his JS25 home and retain third place despite only have three wheels firmly attached to the car, with the front left wheel bouncing up and down over the course of the last lap, but somehow remaining attached to the car. It would remain a career best finish for Streiff. Guy Ligier, not impressed that Streiff had almost taken out both team cars at the end of the race when they were both assured of a podium finish, would not offer the Frenchman a drive for 1986 as a result. The JS25 was replaced for the season by the Ligier JS27.
