Double de-clutch is a method used to make a smoother downshift with less wear. It was a custom of older cars or race cars, with dog-gearboxes that had no synchronizers. In a modern synchro-gearbox, it is only used in unique cases, like when making a [[J-Turn]] without locking up the tires.

The procedure includes declutching, shifting into neutral, re-engaging the clutch, maybe [[rev-up]] the engine by dabbing the accelerator in between ("midway throttle"), and than de-clutch again and shift into the appropriate gear.
