These bushes are part of the rear wheel hub / rear wheel carrier assembly – OE reference numbers: 99133111103 (-104/-105) and 99133111203 (-204/-205).
This 4-piece bushing set combines the big and small concentric bushes in Sport version (85 Shore rating). Designed for direct replacement of the concentric bushes at the rear wheel carrier (hub) mounts, it provides balanced support and consistent suspension behaviour across both rear sides of the vehicle.
2× PR52052P - Sport version Big rear wheel carrier concentric bushes - control arm mount
2× PR52053P - Sport version Small rear wheel carrier concentric bushes - shock absorber mount
All components are made from Prekom’s endurance-tuned rubber compound, stiffer than stock to improve rear handling response without sacrificing durability.
These concentric bushes serve as suspension mounting interfaces between the rear wheel carrier (hub) and the suspension arms / shock absorber mounting points. The sport compound reduces unwanted deflection under load, improves rear wheel alignment stability, and provides a more direct feel through corners and during dynamic driving.
As vehicles age and accrue mileage, stock rear suspension bushes can soften, crack, or lose damping consistency. Worn bushes can lead to:
• Rear wheel carrier play or loose feel under cornering
• Increased body roll Uneven tyre wear
• Less precise rear handling response
Upgrading to a sport-version bush set from Prekom restores proper support and reduces unwanted movement, giving the rear end a tighter, more controlled feel, particularly beneficial for dynamic road driving or occasional track use.
Consider replacing your rear wheel carrier bushes when:
• You feel slop / looseness in the rear end during cornering
• The rear suspension produces clunks or knocks
• Tyre wear is uneven across the rear wheels
• You’re tuning suspension for more responsive handling
• Bushes appear cracked, hardened, or deteriorated

These bushes are part of the rear wheel hub / rear wheel carrier assembly – OE reference numbers: 99133111103 (-104/-105) and 99133111203 (-204/-205).
This 4-piece bushing set combines the big and small concentric bushes in stock hardness. Designed for direct replacement of the concentric bushes at the rear wheel carrier (hub) mounts, it provides balanced support and consistent suspension behaviour across both rear sides of the vehicle.
2× PR52046P - Stock version Big rear wheel carrier concentric bushes - control arm mount
2× PR52047P - Stock version Small rear wheel carrier concentric bushes - shock absorber mount
When fitted together as a set, these bushes restore proper rear hub support and alignment that can be compromised by aged or worn bushes on high-mileage cars.
Function:
The concentric mounting bushes allow the wheel carrier to pivot under load while maintaining precise positioning. The stock-hardness compound strikes a balance between comfort and control - providing road-friendly compliance without excess deflection. Correct rear hub support contributes directly to predictable handling, tyre life, and vehicle stability.
Over time, factory bushes can harden, crack, or develop play due to heat, load cycles, and mileage. Worn concentric bushes may produce:
• Rear suspension noise (clunking / knocking)
• Vague handling or rear instability Uneven tyre wear
• Reduced alignment precision
Replacing all four bushes simultaneously ensures even support on both sides of the rear suspension, eliminates unwanted play, and restores confident vehicle dynamics under everyday and spirited driving conditions.
When to replace.
These concentric bushes should be considered for replacement if you notice:
• Clunking or knocking from the rear suspension over bumps
• Loose or imprecise rear end response
• Visible cracking or rubber deterioration on existing bushes
• Rear wheel alignment issues
• Preventative maintenance during rear suspension overhaul

Fits number 1 on the diagram.
Parts highlighted in green on the diagram.
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

This is a sport-spec concentric suspension bushing engineered to replace the original equipment rear wheel carrier bushing on Porsche 991 vehicles. It is manufactured to strict European quality standards and designed to replicate the OE part’s dimensions while offering a firmer compound specifically tuned for enhanced dynamic performance.
The concentric bush fits between the rear wheel carrier (hub) and the rear suspension arm mount. It secures the wheel carrier in place while allowing controlled movement with suspension travel. The sport version’s firmer rubber compound reduces unwanted deflection under load, improving stability, turn-in precision, and overall rear suspension feedback.
Worn or degraded bushes in the rear suspension can lead to:
• Loose or imprecise handling
• Clunking or knocking noises over bumps
• Uneven tyre wear
• Reduced rear stability under dynamic driving
The Prekom big sport version bush (PR52052P) uses a sport-tuned rubber compound that strikes a balance between daily comfort and performance driveability. Compared with stock bushes, it offers a more direct connection with less unwanted movement, helping the rear suspension maintain tighter geometry and a sharper feel without sacrificing durability or longevity.
When to replace
Replace this rear wheel concentric bush when you observe any of the following:
• Noticeable play in the rear wheel hub
• Knocking/clunking sounds from the rear suspension
• Rear end feels loose or unstable
• Visible cracking, splitting, or material degradation
• During complete suspension overhaul or when upgrading ride performance

This is a rear wheel carrier concentric bushing (control arm mount – big size) made as a stock (OEM-style) replacement for the original Porsche rear hub mounting bushes. It conforms to stock dimensions and material properties, delivering reliable performance consistent with factory standards.
The concentric bush sits between the rear wheel carrier (hub) and the control arm mounting point. It absorbs vibrations, reduces unwanted movement in the suspension, and maintains correct wheel alignment geometry under normal driving conditions. By securely locating the hub relative to other suspension members, it helps ensure stable handling and tyre contact with the road.
As part of the rear suspension assembly, this bush allows controlled rotation of the wheel carrier while reducing noise, harshness, and vibration. Its stock-level stiffness provides a balance of comfort and stability suitable for everyday road use, maintaining proper suspension dynamics without the harsher feel of sport or motorsport variants.
Over time, suspension bushes can age, harden, or deteriorate due to heat, load cycles, and environmental exposure. Worn bushes may allow excess play in the rear wheel carrier, leading to:
• Clunking or knocking noises from the rear suspension
• Loose or imprecise handling Uneven tyre wear
• Misalignment of the rear wheel carrier
Replacing worn bushes with a stock-version concentric bush restores proper support at the hub mount, helping maintain smooth ride quality, stable steering response, and predictable rear suspension behaviour.
Consider replacing this rear wheel concentric bush if you notice any of the following:
• Play or looseness in the rear wheel assembly
• Knocking or clunking noises from rear suspension
• Vehicle feels unstable or vague in rear end handling
• Physical signs of rubber degradation, cracking, or splitting
• During rear suspension service, alignment work, or control arm replacement

Concentric bushes wear with age and mileage. Hardened, cracked, or deteriorated bushes can allow excess movement in the rear wheel hub, which may cause:
• Clunking or knocking noises from the rear suspension,
• Increased body roll or vague handling,
• Uneven tyre wear,
• Reduced stability under braking or cornering.
The sport version PR52053P uses a stiffer rubber compound than stock to provide more precise control while still offering compliant ride quality - making it ideal for drivers who want sharper feel without jumping to full motorsport components.
Replace this rear wheel carrier concentric bush if you notice any of the following:
• Noticeable play or looseness in the rear hub under load
• Clicking/knocking sounds from the rear during acceleration, braking, or over bumps
• Rear handling feels imprecise or soft
• Visual signs of cracks, splits, or material deterioration
• You’re upgrading to sportier suspension behaviour

The PR52048P is a motorsport-grade concentric monoball unit designed for the rear wheel carrier (hub) control arm mount on Porsche 991 vehicles. Built with precision engineering and performance materials in Europe, it replaces the conventional rubber suspension bush with a hardened spherical bearing for maximum control and responsiveness.
Installed at the rear wheel carrier to control arm mount, the monoball reduces compliance that is inherent in traditional rubber bushes. By replacing rubber with a spherical bearing, it ensures the hub remains precisely located relative to suspension loads - even under high lateral and longitudinal forces. This significantly improves handling consistency and repeatability during aggressive driving.
Rubber suspension bushes, while comfortable for everyday driving, can flex and deform when subjected to high cornering forces or track load. This compliance can lead to:
• Reduced suspension precision
• Vague handling at the limit
• Unwanted changes in camber and toe settings under load.
This motorsport monoball replaces that compliant interface with a hardened spherical bearing, virtually eliminating bush flex and delivering a more direct, predictable response - ideal for track days, competition use, and drivers who demand precise rear-end control.
When to replace
Consider this upgrade or replacement if:
• You are building a track-focused suspension setup
• You experience unwanted rear wheel carrier movement at high loads
• You want to reduce compliance and improve mechanical feedback
• Rubber bushes are worn, cracked, or allowing excessive play

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.
