Rear wheel concentric monoball / Rear hub monoball set (2 small + 2 big), Motorsport version. Porsche 991 2012>>  ❭  PR52056P

Rear wheel concentric monoball / Rear hub monoball set, Motorsport / racing version.
This 4-piece rear wheel carrier concentric monoball set is a motorsport-grade suspension upgrade designed to replace the stock rubber bushes in the rear suspension of Porsche 991 models. The spherical bearing construction in both small (PR52049P) and big (PR52048P) monoballs eliminates unwanted compliance and delivers extremely rigid support where the suspension attaches to the wheel carrier (hub) and shock absorber mount.

These bushes are part of the rear wheel hub / rear wheel carrier assembly – OE reference numbers: 99133111103 (-104/-105) and 99133111203 (-204/-205).

This set is ideal for drivers focused on performance driving, track days, or aggressive road use, where precision and repeatability under load are critical.
It combines:
 2× PR52048P -  Motorsport / Racing version Big rear wheel carrier concentric bushes - control arm mount
 2× PR52049P - Motorsport / Racing version Small rear wheel carrier concentric bushes - shock absorber mount

With hardened bearings and precise tolerances, this set ensures maximum retention of alignment angles and suspension responsiveness while minimising unwanted movement in high-stress driving conditions.

The monoball units remove the flex present in stock bushes by replacing rubber material with high-strength spherical bearings that secure the hub and shock absorber mounts. This results in:
•  Sharper handling response
•  More consistent rear wheel alignment
•  Improved feedback and control under cornering
•  Reduced deflection under high lateral and longitudinal loads.

Unlike conventional bushes, monoballs provide minimal deformation under load, keeping suspension geometry stable and predictable.

Rubber bushes are designed for comfort and everyday use but will deflect under aggressive driving loads, which can cause:
•  Unwanted suspension compliance
•  Rear end vagueness under cornering
•  Uneven tyre wear
•  Reduced alignment stability under load.

By replacing them with motorsport-grade monoballs, this set dramatically increases rear suspension stiffness and responsiveness - ideal for track enthusiasts, performance upgrades, or drivers seeking ultimate precision from their rear end.

When to Replace / Upgrade Consider this monoball set when:
•  Beginning a track build or performance suspension upgrade
•  You experience unwanted play or deflection in rear end feel
•  Existing bushes are worn, cracked, or softened
•  You want more direct feedback and sharper handling
•  You are performing rear suspension overhaul
