Keep your car level through the corners with the Garagistic E30 rear sway bar available in 3 different sizes: 16mm, 19mm, and 22mm. Sway bars link the left and right sides of your car's suspension helping to balance the car and keep it more flat through the corners and over the bumps. As a car rolls and the suspension arms move your tires and change the way they contact the road, using a sway bar can help mitigate this and hold more consistent contact with the road. This means that a properly set up car with sway bars will have more grip and be more predictable!
