A crackdown on hoon drivers has seen police confiscate nearly 750 vehicles in July alone.
The month-long State traffic unit operation targeting hoon behaviour and dangerous driving has led to 744 vehicles being seized, including 635 for motorists driving without a licence.
A weekend sting on car clubs in the Perth Hills resulted in 115 speed-camera infringements and 11 on-the-spot fines.
Two vehicles were impounded because the driver's had no authority to drive, while another car is expected to be impounded after the driver was clocked allegedly travelling at 133km/h in a 60km/h zone in Maida Vale.
Sen. Sgt Chris Hannan said the vast majority of the approximately 70 known car clubs in Perth were law abiding, but some members at specific clubs were "lunatics on the road" who "thumbed their nose at society".
"They're the ones the car clubs are trying to push out as well because they're bringing bad media attention towards them," Sen. Sgt Hannan said.
"There is a small percentage that when they get together the testosterone gets very high and they are arrogant on the road and that's when they speed, drive dangerously and put all road users at risk.
"We're encouraging the community to give us information of where these clubs are meeting, the routes they're taking and we will police those ... and systematically break the cars club's runs up."
In two separate incidents along Indian Ocean Drive on Saturday two men were caught speeding. A 23-year-old Geraldton man was allegedly travelling at 181km/h in a 110km/h zone about 11.15am. The man's vehicle was seized for 28 days and he will face reckless driving charges.
Later in the day, a 19-year-old man was detected travelling towards Jurien Bay at 176km/h in a 110km/h zone.
"As police conducted a u-turn (to stop the offending vehicle) the vehicle lost control and went into bushland," Sen. Sgt Hannan said.
"The driver was OK, he was taken to Joondalup Health Campus. His vehicle will be subject to a surrender notice."
