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
