Product Information
Control arm lower, Rear.
This OE Match suspension set includes two rear lower control arms (2 × 98733104304), providing a complete left-and-right replacement for the rear axle of Porsche 987 Boxster and 987 Cayman models. These arms are engineered to replicate the geometry, strength, and bushing characteristics of the original Porsche components, ensuring precise wheel alignment, stable handling, and predictable chassis behaviour.
SET OF 2 - for left and right side.

Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2005 - 2008

This set is ideal for vehicles showing rear-end instability, knocking noises, or alignment issues caused by aged or worn control arm bushings.

•  Part Numbers / Cross-References: 98733104304 (current), 98733104302 / 98733104303 (previous numbers)

• Position: Rear lower control arm / lateral link - connects rear axle assembly to chassis/subframe, controlling wheel lateral and longitudinal position under dynamic loading.

 Functions: Maintains correct wheel alignment geometry under load, ensures stable rear-end handling, helps manage camber and toe changes, absorbs suspension loads, supports consistent tyre contact and handling predictability.

The rear lower control arms maintain correct camber and toe alignment during suspension travel. They stabilise the rear axle under dynamic load and help ensure consistent tyre contact and grip. As a matched pair, they work together to deliver the balanced handling and responsiveness expected from a Porsche mid-engine chassis.

Benefits of replacing as a pair:
 Restores identical suspension behaviour on both sides
 Ensures consistent camber and toe alignment
 Eliminates uneven tyre wear caused by mismatched bushings
 Improves high-speed stability and cornering predictability
 Ideal for full rear suspension refresh or alignment correction

With time, the bushings and joints inside these arms deteriorate, causing unwanted movement, clunks, instability and poor alignment. Replacing both arms ensures complete restoration of rear suspension accuracy, improving handling sharpness, road feel and overall safety.

When to Replace:
 Knocking or clunking noises from the rear over bumps
 Excessive play in rear suspension arms during inspection
 Uneven or premature rear tyre wear
 Alignment cannot be maintained (camber/toe constantly shifting)
 Rear-end feels unstable during cornering or acceleration
 Performing a full suspension overhaul

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

This lock nut fits in the suspension assembly, at the control arm to wheel carrier mounting point. 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
  Provides a factory-correct M12 x 1.5 locking fastening point
  Helps maintain suspension arm stability and alignment
  Prevents loosening caused by road vibration and suspension movement
  Supports correct suspension geometry and wheel control
  Helps ensure safe and secure mounting of chassis components
  Provides OE Porsche fitment, thread size and fastening quality.

Control arm lock nuts are exposed to road dirt, moisture, corrosion and high suspension loads. Over time, the nut can corrode, seize, round off or lose its locking ability. Because this fastener secures a critical suspension joint, it is good practice to replace it whenever the control arm is removed or replaced.

Using a Genuine Porsche OE lock nut helps ensure the control arm is correctly secured to the wheel carrier and maintains the factory-standard suspension assembly.

When to replace
  When replacing a control arm, wishbone or coffin arm
  When removing or refitting the arm-to-wheel-carrier joint
  If the original nut is corroded, seized or damaged
  If the thread is worn or the locking function is compromised
  During suspension overhaul or chassis repair work
  After accident repair or wheel carrier replacement
  When restoring the suspension with correct OE Porsche hardware.

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.
