Body roll happens when you turn into a corner. As your car begins to turn, its weight is thrown to the outside of the corner. It causing your car to roll in that direction. Simply, as you turn left you are thrown to the right, and turning right throws you left.
Your wheels are in constant contact with the ground so always stay on the same level but your car’s body and, by extension, the cabin in which you’re sitting sit on top of springs attached indirectly to your wheels. It allowing the car’s body to body roll independently of the wheels.
Now to know how to reduce body roll in a car follow the below steps and also know the cause.

Why Does It Happen?
Centrifugal force is the reason why the body roll happens?. The thing happens when you turn your car. It becomes the weight and the corner becomes the arc the weight takes around your head. As your cornering speed increases, the force pushing you to the outside of the turn increases. These forces are absorbed by your car’s suspension resulting in the body leaning to the outside of the corner.
Why Is Body Roll A Bad Thing?
We often hear that preventing body roll is so important that we must all rush out and buy this product or that product to prevent it. Therefore consequently we accepted that body roll is bad always. But what exactly does body roll do to negatively affect vehicle handling we don’t know.
For starters, it diverts the driver. This is probably the effect that most drivers can see and feel during their own driving experiences. And while this is not the most important negative effect of body roll, indeed, the car does not drive itself. No matter how many aftermarket parts you install.
So keeping the driver settled, focused, and able to concentrate on the task of driving is a foremost priority for spirited vehicle handling. However, the most often misunderstood effect of body roll upon vehicle handling is the effect of body roll upon camber and the effect of camber changes upon tire traction.
Simply, the larger the contact patch of the tire, the more traction exists against the road surface, holding all else constant. But when the vehicle begins to lean or roll to one side, the tires are also forced to lean or roll to one side.
This can be described as a camber change in which the outside tire experiences increased positive camber. This means rolls to the outside edge of the tire. And the inside tire experiences increased negative camber that means rolls to the inside edge of the tire. So a tire that originally enjoyed a complete and flat contact patch before body roll must operate on only the tire edge during body roll.
The resulting loss of traction can allow the tires to more easily give way to the forces of weight transfer to the outside edge of the vehicle. When this happens, the vehicle slides sideways which is generally a bad thing.
How To Reduce Body Roll In A Car?
Excessive body roll can be caused by many different parts of your car not acting properly. But the body roll of a car is not at all bad things.
1. Loose And Worn Suspension System
The suspension system keeps your car smooth and balanced. It connects all four wheels to the body of the car and allows the wheels and body to work in one behind the other. The suspension makes your car one cohesive piece, rather than four separate components. Since the suspension helps hold everything together, it reduces the body roll Because it doesn’t allow all of the force to shift to the outside of the vehicle.
As the suspension wears out and becomes loose, the drive on the car becomes loose as well. This means that the body roll becomes stronger and more noticeable. This is the first way to know how to reduce body roll in a car.
2. Shocks Need Replacing
Like your suspension, your shocks play a key role in helping your car have a ride as smooth as possible. Shocks help limit how much force the body of your car feels. By absorbing a large amount of the impact from the road.
While shocks are primarily associated with absorbing bumps and bounces from the road, they also help with body roll. As the force from turning sharply is applied to the vehicle, the shock springs absorb much of the pressure. And also limit what you feel inside the car.
3. Worn Down Tires Impacts
While your suspension and shocks impact how much body roll your car experiences. Whereas tires impact how your car deals with the body roll. Excessive body roll can make it hard to steer, as your car has a hard time gaining traction on the road and straightening itself out.
If your tires are worn down, and lacking tread, then this impact is magnified. Worn down tires have a very hard time gripping the road, and will make it difficult for your car to handle when facing large amounts of body roll.
4. Modifications To Adverse Impacts
Wheels and shock lift kits are two very common modifications for cars, but both of them can have adverse impacts on how your car handles body roll. A mechanic will be able to tell you if the modifications made to your vehicle are hurting the body roll or not.
This is the best way if you can not find the solution how to reduce body roll in a car by yourself. Take to the mechanics, they will examine better
Anti-roll bars are suspension components design to mitigate body roll. They do this by connecting the wheels at either end of an axle with a torsion bar attached to the vehicle body. Body roll can also be reduced by lowering the center of mass of the vehicle body, fitting stiffer suspension springs, and reducing the sprung mass of the vehicle.
Under normal circumstances, a vehicle’s shocks and struts work to keep the body as stable as possible while driving around curves and taking turns. Body roll refers to the angle that the car’s body tilts, or “rolls”, during that process.
