A genuine Porsche front coil springs. This set includes two front springs, intended to be installed together to maintain correct suspension balance and geometry.
These springs support the full front axle load and control suspension movement during braking, acceleration, and cornering. Calibrated specifically for the listed PR configurations, they ensure correct vehicle stance, consistent ride quality, and predictable handling response.
Installed between the lower control arms and front strut assemblies, the coil springs compress and rebound with suspension travel. Their precisely tuned spring rates work in harmony with Porsche dampers and chassis systems to absorb road impacts, stabilise the vehicle body, and maintain accurate steering and tyre contact.
When to replace:
• Front ride height has sagged or become uneven
• Springs show signs of fatigue, corrosion, or damage
• During front shock or strut replacement
• Suspension refurbishment or alignment correction
• Reduced handling precision or ride quality

Diagram ref no 7
A genuine Porsche front suspension coil spring, manufactured to OEM standards for material quality, dimensional accuracy, and durability. This spring is designed to integrate seamlessly with factory dampers and suspension components.
The coil spring supports the front axle load and controls vertical suspension movement during braking, acceleration, and cornering. It helps maintain correct ride height, balanced weight distribution, and predictable handling response.
Installed between the lower control arms and front strut assemblies, the coil springs compress and rebound with suspension travel. Their sport-tuned spring rates work in harmony with Porsche dampers to absorb road inputs while maintaining increased stability, steering precision, and performance-oriented ride characteristics.
Over time, constant load, aggressive driving, and road impacts can cause springs to weaken or sag, affecting suspension geometry and performance. Replacing worn springs restores factory ride height, handling balance, and the sharp driving characteristics Porsche intended.
When to replace:
• Front ride height appears lower or uneven
• Noticeable increase in body roll or reduced handling precision
• Springs show corrosion, cracks, or fatigue
• As part of a sports suspension refurbishment or alignment correction
