Replacing both sides as a pair ensures symmetrical suspension behaviour, consistent road feedback and balanced camber/toe control — essential for high-performance Porsche chassis dynamics.
These front lower control arms stabilise and locate the front wheels under braking, acceleration and cornering loads. They maintain consistent camber and toe geometry, absorb road vibrations and support precise steering response. As a matched pair, they ensure uniform suspension performance across the front axle.
With age, bushings soften and ball-joint interfaces wear, leading to unwanted movement, clunks, steering imprecision and alignment drift. Replacing both arms restores accurate suspension control, improves safety and brings back the crisp, predictable handling Porsche models are known for.
When to replace:
• Steering feels vague, unstable or wanders
• Knocking/clunking noises from the front suspension
• Uneven or accelerated front tyre wear
• Alignment cannot be held after adjustment
• Visible cracks or deterioration in control arm bushings
• Following installation of new shocks, springs or front suspension components

What’s Included:
• 2x 99134104306/3 – OE Match Front Control Arms
These front lower control arms (wishbones) are manufactured to OE match specification, ensuring the same geometry, fit and performance as the original Porsche part. They provide stability, absorb road forces and help maintain accurate wheel alignment.
• 2x 99134105306/3 – OE Match Front “Coffin Arms”
Named for their distinctive shape, these arms are critical for controlling camber, caster and steering behaviour. Worn coffin arm bushes are a common cause of knocks, vibration and vague steering response — replacing them restores crisp, precise front-end dynamics.
• Genuine Porsche Fitting Kit (bolts and nuts) A complete set of new Porsche fasteners for correct installation. Suspension bolts and lock nuts should not be reused, as they are torque-to-yield and essential for maintaining clamping force and safety.
This complete kit renews the entire lower front control arm assembly, allowing you to:
• Restore factory steering precision and handling stability
• Correct alignment issues caused by worn bushes or elongated joints
• Eliminate knocking, squeaking or vibration from the front suspension
• Ensure safe and reliable installation using fresh genuine Porsche hardware.
Front control arm bushes and ball joints wear over time due to road impacts, driving style and age. Symptoms include:
• Steering play or “loose” front end feel
• Uneven tyre wear
• Vibration or knocking over bumps
• Poor tracking or pulling to one side
• Instability under braking
Replacing all four arms together ensures even wear, consistent geometry, and the best long-term results, especially when pairing with a fresh alignment.

The rear control arm plays a vital role in the suspension system by:
• Supporting lateral and longitudinal forces
• Keeping the wheel aligned relative to the chassis
• Allowing controlled suspension movement
• Helping maintain correct wheel camber and toe angles.
This improves handling precision, reduces unwanted tyre wear, and enhances ride stability.
Control arms are subjected to constant load and movement, which over time can lead to:
• Worn or torn bushings
• Excessive play in the arm joint
• Loose or imprecise handling
• Uneven tyre wear
• Suspension noise and reduced comfort.
Replacing worn or fatigued control arms helps restore factory handling characteristics, maintain correct alignment, and protect adjacent suspension components from accelerated wear.
Replace the rear control arm if:
• Excessive vibration or instability is felt during cornering
• There is noticeable play or looseness in the rear suspension
• Uneven tyre wear is observed
• Control arm bushings are cracked or damaged
• During rear suspension overhaul or alignment issues

Diagram ref No 5
• Position: Front axle — lower control arm / track bar (left or right side).
• Role in Suspension: Controls wheel alignment (camber, toe), locates the front wheel assembly under dynamic loads, absorbs road forces, and helps maintain stable handling during braking, acceleration and cornering.
• The front control arm maintains precise positioning of the wheel relative to the chassis, ensuring correct suspension geometry under load. Its bushings isolate road vibrations while allowing controlled suspension movement, preserving both ride comfort and steering accuracy. As a direct-fit replacement, it restores proper front suspension behaviour without the need for modifications.
With age and mileage, the bushings and ball-joint in the control arm gradually wear due to road stress, heat, and repeated load cycles. This can lead to vague steering, poor straight-line stability, uneven tyre wear, knocking noises, or difficulty holding correct alignment. Replacing the arm ensures tight, predictable suspension response and safer, more controlled driving dynamics - especially important for high-performance vehicles or those driven hard.
When to replace:
• Noticeable knocking or clunking from front suspension over bumps or braking
• Loose or vague steering feel, especially at speed
• Uneven or premature tyre wear on front tyres
• Difficulty achieving or maintaining correct wheel alignment (camber/toe)
• Excessive play discovered in control arm joint on inspection
• Completing other suspension work (bushings, shocks, struts) - good practice to renew suspension links together

OEMatch Track Control Arms FRONT — Control, Stability, Comfort
OEMatch front track control arms for Porsche models are replacement suspension items designed to preserve steering geometry and alignment. They are intended for routine service, restoration and suspension setup work where accurate front-end control is required across road and track use.
Available Types
- Standard replacement arms with bonded bushes for factory-style fit and feel
- Adjustable control arms to assist precise suspension alignment during setup
- Performance arms with polyurethane bushes and reinforced joints for heavier use
Understanding OEMatch Track Control Arms
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. Track control arms connect the chassis to the steering knuckle, control wheel position under load and influence camber, castor and toe during dynamic conditions. OEMatch maintains a wide catalogue of Porsche suspension parts and related hardware to support maintenance and repairs.
Benefits Include
- Restore accurate front suspension geometry and steering response
- Reduce uneven tyre wear and road-induced vibration
- Improve braking stability and cornering control
Why Track Control Arms Wear and Fail
- Perished or worn bushes that allow unwanted movement
- Ball joint wear leading to play or knocking noises
- Corrosion, impact damage or metal fatigue from stress
The Importance of Replacing with OEMatch Track Control Arms
Replacing worn or damaged front track control arms restores alignment accuracy, steering precision and vehicle stability. Timely renewal prevents progressive tyre wear, reduces handling unpredictability and ensures braking loads are transferred as intended for safer, more consistent road behaviour.
Advantages
- Direct-fit replacements engineered to match original dimensions and tolerances
- Options with rubber or polyurethane bushes to suit different ride preferences
- Reinforced joints and corrosion-resistant finishes to support service longevity
