Dozens of drivers face prosecution after racing their cars at speeds of up to 80mph on a dual carriageway close to the Lakeside shopping centre on Saturday.
Essex Police said officers used unmarked cars fitted with video recording equipment to identify those taking part in a "drifting" event.
Offenders have been identified through vehicle index numbers and they will be summonsed to court for speeding and road racing offences, the force said today. SEE FOOTAGE FROM SATURDAY'S EVENT HERE (WARNING: CONTAINS LANGUAGE SOME MAY OFFENSIVE.
Sgt Simon Willsher said: "Cruiser events in Essex are usually good-natured and enjoyed by hundreds of enthusiasts who meet to show off their cars and talk about their hobby.
"But there is always the minority of drivers who take part in illegal street racing and drifting events, putting their own lives and the lives of spectators at risk.
"These speeding cars were passing only inches from spectators who had no crash barriers or railings to protect them had any of those cars crashed out of control.
"We will continue to act robustly to deal with drivers who break the law while taking part in these events."
