Mini Cooper S R57 Cabrio Front Right O/S Spring Strut Suspension Leg Brake

The MINI R57 S Cabrio Strut and Knuckle Assembly Right N14 is a complete component from the Suspension Replacement Kits group, designed for the front axle on the right side of Mini vehicles. Integrating the strut with the knuckle simplifies servicing, reduces assembly time, and allows for the restoration of correct suspension geometry without the need to select individual components.

Intended Use and Fitment for MINI R57 S Cabrio

The presented strut-knuckle assembly has been developed for the S Cabrio version with the N14 engine, meaning its construction is adapted to higher loads and the suspension characteristics typical of sporty Mini variants. Its placement on the vehicle is the front right side, making this component responsible for wheel guidance, maintaining the correct camber angle, and stable vibration damping in this corner of the body.

Construction and Function of the Strut-Knuckle Assembly

The combination of the strut and knuckle in a single assembly ensures cohesive operation of the entire suspension corner. The knuckle serves as the mounting point for the wheel hub, steering system components, and the strut mount, while the strut itself is responsible for controlled damping of spring and body movements. This configuration:

• facilitates the maintenance of factory suspension geometry,
• reduces the risk of improper part fitting,
• allows for faster diagnostics and replacement of the entire assembly in case of mechanical damage.

Thanks to this solution, factory driving characteristics can be predictably restored, which is important for both comfort and vehicle stability at higher speeds.

Application in Mini Suspension System

This component belongs to the Suspension Replacement Kits group, meaning it is intended for comprehensive servicing of a given corner – from wheel guidance, through cooperation with the steering system, to damping of unevenness. In practice, this translates to:

• more predictable vehicle behavior during braking and acceleration,
• more stable trajectory maintenance in corners,
• reduction of unwanted play and vibrations transmitted to the body.

For the S Cabrio version, maintaining the appropriate stiffness of the front axle is also important to preserve the characteristic dynamic response to steering inputs.

Characteristics of Used Part

The offered component is in Used condition, meaning it comes from disassembly and has been verified for further operational suitability. Choosing an original used strut-knuckle assembly for Mini allows for the preservation of the factory design and operating parameters, while also reducing costs compared to purchasing a new component. This solution is particularly beneficial for post-accident repairs or restoring the vehicle to full functionality after mechanical suspension damage.

Benefits of Using a Complete Suspension Kit

The use of a complete assembly for the front right side offers a number of practical advantages:

• reduced risk of incompatibility between separately selected parts,
• easier geometry alignment after installation,
• consistent damping and wheel guidance on one side of the vehicle,
• possibility of faster replacement in workshop conditions.

For the user, this means more stable handling, better vehicle control, and reduced additional costs associated with multiple adjustments or replacement of individual sub-assemblies.
