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
