Product Information

This OE Match lower control arm centre solid bush is intended for Porsche 986 Boxster and 996 suspension applications. Supplied individually, it replaces the bush rather than the complete wishbone.

Fits

Porsche 986 Boxster
Porsche 996 1997-05

When using in 997/987 requires spacers/shims

Check fitment for your specific vehicle (model, year, engine) before ordering.

What This Product Does

The centre bush forms part of the lower control arm connection, supporting the arm's location as suspension loads change. It is intended for suspension refurbishment or a revised bush specification on vehicles used on the road and track.

Functions

Provides the lower control arm's central bush connection.
Supports controlled movement at the associated suspension joint.
Replaces a worn or damaged centre bush within a serviceable arm.

Technical Details

Component: lower control arm centre solid bush, not a complete arm.
Specified material: aluminium, grade 6082-T6.
Supplied specification states a 25% durometer increase; the comparison baseline and absolute hardness are not specified.
Quantity supplied: one bush.

Symptoms of Fault

Bush wear may be associated with knocking or creaking, indistinct steering, vibration, uneven tyre wear or pulling during braking. These symptoms can also originate from ball joints, track rods, drop links or mounts, so inspect the complete assembly before selecting replacement parts.

Why Replacement Matters

Renewing a worn bush addresses unwanted movement at its connection. Check the arm, ball joint and adjoining hardware at the same time; a new centre bush will not correct wear elsewhere. Choose the bush specification to suit the intended suspension setup rather than assuming identical comfort characteristics to the original component.

FAQs

Is wheel alignment necessary afterwards?
Have suspension geometry checked following the work and adjusted where required.

Should the opposite side be inspected?
Yes. Assess both sides for comparable wear and inspect nearby joints before deciding the extent of the repair.

Does this directly fit a 997 or 987?
The supplied installation note requires spacers/shims for those models. Confirm the specific arm and installation requirements first.

Product InformationProduct Information
Control arm, Front
These Porsche Genuine OE Front Control Arms (Part Nos. 99134104187 Left & 99134104287 Right) are original factory front suspension wishbones / lower control arms designed for Porsche 991 GT3, 982 Boxster Spyder and 982 Cayman GT4. Complete with integrated bushes and ball joints, they ensure precise steering response, stable suspension geometry, and factory handling characteristics both on road and track. As genuine Porsche parts, they guarantee exact fitment, durability, and OEM-level chassis performance.

Fits:
Porsche 991 GT3 2014 - 2021
Porsche 982 (718) Boxster Spyder 2019>>
Porsche 982C (718C) Cayman GT4 2019>>

Diagram ref No 6

The control arms connect the wheel carrier to the front axle subframe, controlling suspension movement during:

• Steering input
• Braking
• Cornering
• Suspension compression and rebound

They maintain correct wheel alignment and suspension geometry while ensuring precise steering response and high-speed stability.

The integrated ball joints allow smooth articulation, while the suspension bushes absorb vibration and road harshness without compromising the sharp handling characteristics expected from Porsche GT models.

Functions & Technical Role
•  Suspension geometry control: Maintains accurate wheel positioning and alignment
•  Steering precision: Supports sharp and responsive steering feel
•  Integrated ball joints: Allow controlled suspension articulation
•  Vibration damping: Bushes reduce harshness and unwanted movement

•  GT chassis stability: Designed for high-performance driving and track use
•  OEM engineering: Manufactured to Porsche factory tolerances for exact fitment and durability

The front control arms play a major role in steering accuracy, suspension stability, and tyre wear control. Worn bushes or ball joints can negatively affect handling precision and overall driving dynamics.

When to replace
•  Knocking or clunking from the front suspension
•  Excessive play in bushes or ball joints
•  Uneven tyre wear or alignment issues
•  Steering instability or vague handling
•  During suspension rebuild or track-preparation work
