Purpose and function in the suspension

The presented set belongs to the Leaf and Coil Springs category and is dedicated to the rear axle of the BMW 3 Series E91 Touring body style. The components operate on both sides of the vehicle – left and right – and are responsible for maintaining the correct ride height, supporting loads, and working in tandem with the shock absorbers throughout the entire suspension travel range.

Selecting original springs is crucial for maintaining factory handling characteristics, even load distribution on the rear axle, and the proper operation of safety systems such as ABS and traction control.

Benefits of using the original set

Using a complete, matched set of springs for the rear axle allows you to:

• maintain consistent, predictable vehicle behavior in corners,
• preserve the correct ride height under typical trunk and rear seat loads,
• reduce the risk of uneven tire wear on the rear axle,
• ensure proper cooperation with stock shock absorbers and other suspension components.

As a result, the car retains its signature BMW character – precise handling, stability at higher speeds, and confident reactions to steering inputs.

Installation characteristics

The rear spring set is designed for installation in the factory mounting points on the rear axle, on both the left and right sides. The design, compliant with the manufacturer's specifications, facilitates service work and allows for the use of standard installation procedures applied in workshops servicing BMW vehicles.

Replacing both springs on the axle simultaneously is recommended to maintain suspension symmetry, even deflection on both sides, and consistent vehicle reactions during braking, acceleration, and driving over uneven surfaces.

Condition and origin

The offered set comes from the original BMW line, which ensures the preservation of factory design parameters and compatibility with the E91 Touring platform. The components are used, making them a cost-effective solution for users who want to restore proper suspension performance while sticking to components consistent with the manufacturer's design.
