• 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.

• Position on Vehicle: Rear axle, control arm position linking rear wheel carrier / suspension to chassis, controlling camber, toe and lateral track stability.

• Cross-Reference / Alternative Numbers: OE ref part 981 331 053 02; also referenced 99733105301 / 99733105302 / 99733105303 /  98133105300 / 98133105301.

Built to meet factory specification and supplied with a premium ball joint, it restores accurate alignment, improves handling precision and ensures long-term durability.

The rear control arm is a critical component in maintaining rear axle geometry, wheel alignment, and dynamic stability under acceleration, cornering or load. A worn, bent or loose control arm can lead to:
•  Rear instability or wandering at speed
•  Uneven or rapid tyre wear on the rear axle
•  Clunking or knocking noises from the rear suspension
•  Loss of alignment control (camber/toe drift).

Replacing the arm ensures the rear suspension operates as intended, restoring precision and safety.

When and why to replace:
• You hear a pronounced knock or clunk from the rear suspension when hitting bumps or changing direction.
• Rear tyres wear unevenly or you cannot hold rear alignment specification.

• Position: Rear axle – rear track rod arms (control links), left and right
• Replaces: Porsche OE part 98133104503

Replacing the arms as a matched pair ensures both sides of the rear suspension behave consistently, restoring proper balance and eliminating issues caused by uneven bushing wear. It provides equal camber and toe adjustment range on both sides, making alignment more accurate and stable. The result is improved road feel, better stability under load and more predictable handling in every driving situation.

Rear track rod arms are central to maintaining correct wheel alignment and rear-axle control. Over time, bushings and ball joints degrade, leading to:
• Rear-end instability or “float” at speed
• Excessive or uneven tyre wear
• Clunking or knocks over bumps
• Poor alignment accuracy or inability to hold settings
• Vague or inconsistent handling.

Replacing both arms ensures the rear suspension operates to factory geometry and delivers the crisp, stable driving feel Porsche intended.

About Track Control Arm REAR

Porsche Rear Track Control Arms | Design911 Suspension Components for Alignment, Grip & Handling Stability

Rear track control arms are vital suspension components that maintain your Porsche’s precise wheel alignment, handling balance, and stability under cornering and braking. These arms connect the chassis to the rear wheel hubs, allowing controlled suspension movement while keeping the wheels correctly positioned relative to the road. High-quality track control arms ensure consistent tyre contact, optimal geometry, and the responsive, agile performance that defines Porsche handling.

At Design911, we stock a wide range of rear track control arms and related hardware — precision-engineered for strength, durability, and perfect fitment. Crafted from reinforced steel or lightweight aluminium alloys, these components provide lasting rigidity and improved performance. Whether for suspension servicing, alignment correction, or performance upgrades, our control arms restore confidence, stability, and cornering precision to your Porsche.

What Do Rear Track Control Arms Do?

Rear track control arms play a key role in ensuring stable suspension geometry and consistent handling.

Core Functions:
• Maintain rear wheel alignment and suspension geometry.
• Control lateral and longitudinal wheel movement.
• Enhance traction, grip, and cornering stability.
• Distribute load and stress evenly across the chassis.
• Reduce vibration and improve overall ride comfort.

Properly functioning track control arms ensure precise steering response, improved grip, and the balanced handling Porsche vehicles are renowned for.

Why Do Rear Track Control Arms Fail or Degrade?

Rear control arms are subject to high loads, constant motion, and environmental exposure, which lead to wear or fatigue over time.

Common Causes of Failure Include:
• Worn or perished rubber or polyurethane bushes.
• Corrosion weakening the arm’s structure.
• Ball joint wear leading to play or noise.
• Impact damage from potholes or curbs.
• Fatigue or cracking under heavy cornering forces.

When rear control arms wear or fail, symptoms can include uneven tyre wear, vibration, poor handling stability, and rear-end noise — all of which affect safety and performance.

Why Replace or Upgrade Your Porsche Rear Track Control Arms?

Replacing worn control arms restores your Porsche’s precise handling, ride comfort, and alignment accuracy. Upgraded arms offer stiffer construction and improved adjustability for performance driving or track use.

Key Benefits:
• Restores correct wheel alignment and suspension geometry.
• Improves traction, cornering balance, and braking stability.
