What is Oversteer?
Oversteer occurs when the rear tires lose grip and the vehicle's rear end slides outward, causing the car to turn more sharply than intended. This phenomenon is commonly experienced during high-speed cornering or when abrupt steering inputs are made. In simpler terms, it's when the back of the car wants to overtake the front, resulting in a drift-like motion.
Types of Oversteer
- Power Oversteer: This occurs when excessive throttle application overwhelms the rear tires' grip, causing them to break traction and spin.
- Lift-Off Oversteer: When lifting off the throttle mid-corner, the weight transfer to the front of the vehicle reduces rear tire grip, leading to oversteer.
- Trail-braking Oversteer: Aggressive braking while entering a turn can shift weight to the front tires, reducing rear grip and inducing oversteer.
Causes of Oversteer
1. Weight Distribution
Vehicles with rear-weight bias, such as rear-wheel-drive sports cars, are more prone to oversteer. The weight transfer during acceleration or deceleration can unsettle the rear end, causing it to break traction.
2. Excessive Speed
Entering a corner too fast can overload the tires' lateral grip capabilities, leading to loss of traction at the rear and inducing oversteer.
3. Sudden Steering Inputs
Abrupt steering inputs, especially in high-performance vehicles with sensitive steering systems, can upset the balance of the car and provoke oversteer.
4. Tire Conditions
Worn or improperly inflated tires have reduced grip, increasing the likelihood of oversteer, especially under aggressive driving conditions.
5. Suspension Setup
Stiffer rear suspension settings or imbalanced damping can promote oversteer tendencies by reducing rear tire grip relative to the front.

How to Overcome Oversteer
1. Gentle Steering Corrections
When oversteer occurs, avoid sudden or drastic steering inputs that could exacerbate the situation. Instead, make smooth and gradual corrections to realign the vehicle's trajectory.
2. Countersteering
To regain control during oversteer, turn the steering wheel in the direction of the skid. This technique, known as countersteering, helps to stabilize the vehicle by aligning its direction of travel with the rear-wheel slip angle.
3. Modulate Throttle and Brakes
Carefully manage throttle and brake inputs to redistribute weight and regain traction. Gradually easing off the throttle or applying light braking can help shift weight forward, restoring balance to the car.
4. Practice
Like any driving skill, overcoming oversteer requires practice and familiarity with your vehicle's handling characteristics. Consider attending performance driving schools or practicing in a controlled environment to hone your abilities.
5. Proper Maintenance
Regularly check and maintain your vehicle's tires, suspension, and alignment to ensure optimal grip and stability. Addressing any issues promptly can mitigate the risk of oversteer.
