You don’t want the rear wheel to lock up otherwise it slides out from underneath you all too quickly. The rear has to keep turning and that’s where the slipper clutch helps. If you don’t have a slipper clutch you fan the clutch to control the slide.
Car drifters very rarely use compression lockups to get the car sideways these days, it’s extremely hard on the drive train and they mainly use a hydraulic handbreak then lots of horse power to control and maintain the slide.
Get some motard wheels and have a go mate, it’s fun.
There’s a track at Marulan, near Goulburn. I plan to go to one of the ride days down there in the next couple of months.
