• Position on Vehicle: Rear axle — lower control arm (support/fork), left + right
• Function: Controls rear wheel-carrier movement, maintains geometry and supports precise alignment
Replacing both arms as a matched pair ensures the rear suspension behaves consistently on both sides, preventing imbalance caused by uneven bushing wear. It provides equal camber and toe adjustment range, making alignment more accurate and stable. The result is improved rear-end stability, better cornering feel and more even tyre wear.
When and why to replace:
• You experience clunks or knocking from the rear when going over bumps or during cornering.
• Uneven wear on rear tyres or inability to keep rear alignment within spec.
• Bushings or joints show play or corrosion.
• The vehicle is high-mileage or has been subjected to high stress, track use, or suspension removal.
• As part of a full rear-suspension refresh or rebuild.

The lock nut fastens the control arm to the wheel carrier, helping keep the suspension arm securely mounted in its correct position. This connection is important for maintaining suspension geometry, wheel alignment, and stable handling. Depending on the model, it may be used on front or rear suspension arm connections where Porsche specifies an M12 x 1.5 locking nut.
Functions
• Secures the control arm to the wheel carrier
• Helps maintain correct suspension alignment and geometry
• Supports stable wheel location during driving, braking, and cornering
• Helps prevent loosening caused by road vibration and suspension movement
• Provides a secure OE Match replacement for the original lock nut
• Suitable for suspension repair, control arm replacement, or wheel carrier service
Suspension lock nuts are safety-critical fasteners and may lose locking strength after removal. They can also become corroded, damaged, rounded, or worn over time. Replacing the lock nut during suspension work helps ensure the control arm is secured correctly and reduces the risk of loosening after reassembly.
When to replace
• This Part The control arm has been removed or replaced
• The wheel carrier or suspension arm connection has been dismantled
• The original nut is corroded, damaged, rounded, or seized
• The nut no longer tightens or locks correctly
• Suspension repairs or alignment-related work are being carried out
• There is play, looseness, or noise from the control arm mounting area
• As recommended during service where single-use locking hardware is removed

• Position on Vehicle: Rear axle, lower control arm (support link) that positions and controls the rear wheel hub/wheel carrier relative to the chassis sub-frame.
• Applications: Recommended when the original control arm is bent, corroded, has worn bushings/joints or when you’re renewing the rear suspension to restore handling performance and tyre wear.
The rear lower control arm is a key component in maintaining wheel alignment, suspension stability and tyre contact consistency. A failing or compromised arm can cause poor handling, uneven tyre wear, rear-end instability, and alignment drift. Replacing helps restore original ride and handling precision.
When and why to replace:
• You experience clunks or knocking from the rear when going over bumps or during cornering.
• Uneven wear on rear tyres or inability to keep rear alignment within spec.
• Bushings or joints show play or corrosion.
• The vehicle is high-mileage or has been subjected to high stress, track use, or suspension removal.
• As part of a full rear-suspension refresh or rebuild.

Since the control-arm mounting bolt bears major structural loads and undergoes vibration and torque stress, it can become worn, stretched, corroded or fatigued over time. This reduces its ability to maintain correct alignment and clamping force - potentially resulting in handling issues or component wear. Replacement is especially important when performing rear suspension service, control arm replacement, or alignment work. Installing the correct bolt restores reliable mounting integrity and ensures the rear axle geometry remains stable under load.

• Position on Vehicle: Rear axle, track rod arm / control-link connecting the axle carrier to the body or sub-frame, controlling lateral and longitudinal motion of the rear axle.
• Cross-Reference / Alternative Numbers: OE reference 981 331 045 03, replaces number 981 331 045 02
• Applications: Suitable for replacement when the original link shows wear, has failed bushings/joints, produces rear suspension noise, causes misalignment or uneven tyre wear, or is being renewed as part of a rear suspension service.
The rear track rod arm is a key component in maintaining the correct geometry of the rear axle - the lateral control, alignment setting and load path all rely on it performing correctly. A failing or worn link can result in:
• Unstable rear-end behaviour under cornering or load
• Premature or uneven tyre wear especially on the rear axle
• Noise or clunks from suspension movement under load
• Inability to hold alignment settings or poor road feel
Replacing the component ensures your rear suspension remains factory-accurate, the tyres wear evenly, handling remains sharp and the car instils confidence.
When and why to replace:
• You hear clunking or knocking from the rear suspension when driving over bumps or changing direction
• Rear tyre wear is uneven or alignment cannot be maintained
• The original link shows play in the bushings or joints or is visibly corroded or bent
• During a rear suspension overhaul, axle servicing or after accident damage
• On higher-mileage vehicles where original suspension links have undergone significant service life.

OEMatch Track Control Arm REAR — Control, Stability, Comfort
OEMatch Track Control Arm REAR components for Porsche models are specified to restore rear suspension geometry and handling balance. OEMatch catalogues thousands of Porsche cross-references and offers a wide selection of suspension parts to support maintenance, restoration and alignment work across classic and modern Porsche vehicles.
Understanding OEMatch Track Control Arm REAR
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original track control arms.
OE (Original Equipment) refers to parts matching original specifications for the track control arms and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM track control arms engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. Rear track control arms connect the chassis to the rear wheel hubs and control lateral and longitudinal wheel movement, preserving alignment and tyre contact under load. Their condition influences cornering stability, braking behaviour and ride comfort, so understanding wear and correct specification is important for predictable handling.
Benefits Include
- Restores rear suspension geometry and alignment accuracy
- Improves rear traction and cornering stability
- Reduces uneven tyre wear and vibration
- Available with standard or performance bush options for specific needs
Why Track Control Arms Wear and Fail
- Perished or worn rubber or polyurethane bushes allowing excessive movement
- Corrosion weakening the arm structure and mounting points
- Ball joint wear producing play, noise or loss of control
- Impact damage or fatigue from repeated heavy loading
The Importance of Replacing with OEMatch Track Control Arm REAR
Replacing worn or damaged rear track control arms restores correct wheel alignment, reduces tyre wear and returns handling predictability to your Porsche. Proper replacement supports braking stability and vehicle balance under cornering loads. For maintenance, restoration or preparatory work before dynamic driving, renewed arms help ensure the suspension performs as intended and that alignment settings can be achieved and retained.
Advantages
- Options in reinforced steel or lightweight aluminium designs to suit weight and strength preferences
- Fixed and adjustable designs available to assist alignment correction where required
- Offered with replacement bush or joint options to match repair or performance needs
