Manufactured from high-strength precision-machined aluminium with a durable steel centre sleeve, the solid bushing is engineered to withstand high cornering loads, braking forces and repeated suspension movement without excessive deflection. The eccentric centre design allows accurate suspension geometry adjustment while maintaining secure location of the lower control arm. Designed for direct OE-style installation, it is ideal for performance upgrades, motorsport applications and suspension rebuilds.
What This Product Does:
- Secures the lower control arm to the suspension mounting point.
- Reduces suspension flex under load.
- Maintains more accurate wheel alignment.
- Improves steering precision and front-end response.
- Supports consistent suspension geometry during braking and cornering.
- Provides an eccentric centre for suspension alignment adjustment.
- Restores precise suspension operation.
- Forms an essential part of the front suspension system.
Symptoms Of Wear Or Failure:
- Knocking or clunking noises from the front suspension.
- Excessive movement of the control arm.
- Uneven or accelerated tyre wear.
- Poor wheel alignment.
- Vague or inconsistent steering feel.
- Vehicle wandering under braking or acceleration.
- Cracked, split or deteriorated original rubber bushes.
- Excessive suspension deflection.
- Reduced handling precision.
- MOT or vehicle inspection failure due to worn suspension bushes.
Why Replacement Matters:
- The original lower control arm bushes are subjected to constant braking forces, cornering loads, road impacts and engine vibration. Over time, the rubber material can soften, crack or separate from its housing, allowing unwanted movement that affects suspension geometry and steering accuracy.
- Replacing worn bushes with a solid eccentric centre bushing significantly reduces suspension deflection, allowing the suspension to maintain more consistent alignment under load. This results in sharper steering response, improved braking stability and more predictable handling, particularly on performance-oriented or track-driven vehicles.
- The OE Match Lower Control Arm Eccentric Centre Solid Bushing is manufactured from premium-quality materials to provide factory-style fitment, exceptional strength and long-lasting durability. It is the ideal solution for Porsche suspension upgrades, performance driving, motorsport preparation and professional suspension rebuilds.

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.

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

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
