Why do cars spin?

The simple answer is less traction at the rear than the front.

Well, why does that happen?

Many reasons but here is the most common - LIFT THROTTLE OVERSTEER.

Lift throttle oversteer means that while in a turn the driver suddenly lifts off the gas. This causes weight transfer to the front wheels and away from the rear wheels. The front wheels suddenly gain more traction and the rears suddenly lose it. If the rears lose enough then the rear end of the car goes straight but the front turns and voila - spin.

Similar results can also be generated by sudden release of clutch in a turn, sudden brake application in a turn, sudden unwinding of the wheel when the front end is pushing.

The second biggest cause is - POWER ON OVERSTEER.

Power on oversteer is caused but too sudden an application of the throttle while turning. The accelerative force of the motor combined with the force of the turn exceeds the grip of the tires and around you come.

Note that all of these are driver preventable errors. Looking to solve the problem by changing something with the car is the wrong place to start. Traction control will NOT spin your car but you can.
