Pepsi 300
Oran Park, NSW (20/8/1989)
Circuit Length: 2.62 km
Race Distance: 1 hour (115 laps)
Weather: Cloudy
Miedecke wins! The Kenwood Sierra is the only front-running Sierra to last the distance; Brock retires with a suspected blown headgasket, Bond lost many laps fixing a broken camshaft seal, and Longhurst was disqualified. Longhurst closed the door on a Miedecke passing attempt, the B&H car spinning after a clash of wheels. A few laps later the wheel broke stranding the car out on the far side of the circuit. Longhurst ran back to the pits to arrange a replacement, which the crew takes out to the stopped car. Before the new wheel can be fitted, Longhurst is disqualified for outside assistance. The Scott/Bartlett Starion had a strong run, at one point leading the race, before suspension failure ended its race.
