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
