before the last few laps from the end. The situation became desperate for Wallace as he tried to fend off Maurico Gugelmin and a fast charging Roberto Moreno.
Eventually at the Ferodo Corner, he outbraked himself and tried to recover quickly as he could but he finished 5th.

His brakes was shot and he left it late to make it around the Ferodo Corner.
