This is an advanced concentric monoball unit developed as a motorsport-spec replacement for the OE rear wheel carrier concentric bushing used on Porsche 991 vehicles. Unlike standard rubber bushes, the monoball features a spherical bearing design that provides minimal deflection, outstanding durability, and direct suspension feedback.

The rear wheel concentric monoball replaces the soft rubber bush at the connection between the wheel carrier and suspension arm/strut mount. It completely eliminates compliance in this joint, allowing for direct transfer of suspension loads with minimal movement, which enhances alignment precision and stability under high-load cornering, braking, and acceleration.

Traditional rubber bushes are designed for comfort and everyday driving. Under high lateral loads, they can deflect, leading to:
•  Slight rear wheel misalignment
•  Vague handling response
•  Reduced feedback to the driver

This motorsport monoball eliminates this compliance by using a precision spherical bearing assembly that holds the rear wheel carrier in a fixed position relative to the control arm. This enhances steering precision, improves feedback, and delivers confidence-inspiring control on track or spirited road driving.

This motorsport version is ideal for:
•  Track days and competitive events
•  Aggressive driving
•  Suspension setups where reduced compliance is critical
•  Drivers seeking maximum handling precision

When to replace. Consider upgrading to monoballs if you experience:
•  Excessive deflection or “mushy” feel in the rear suspension
•  Delayed response under hard cornering
•  Vague rear end feel during acceleration or braking
•  You’re rebuilding or upgrading suspension for track use
•  High mileage or worn stock bushes showing play


•  The motorsport version delivers significant gains in precision but may transmit more noise and harshness than stock or sport bushes — this is normal for competition-oriented parts.
•  Sold individually — 2 per vehicle recommended for balanced installation.
