Product Information
SET OF 2
We strongly recommend replacing coil springs in pairs.
Fits:
Porsche 991.1 Carrera 4 / 4S / 4 GTS 2012 - 2016
Porsche 991.1 Targa 4 GTS 2012 - 2016
* For cars with Standard chassis (option code: 029)
Diagram ref no 10
This spring set supports the full front axle load and manages suspension movement during braking, acceleration, and cornering. Replacing both front springs together ensures even load distribution, symmetrical ride height, and predictable handling characteristics.
Installed between the lower control arms and front strut assemblies, the coil springs compress and rebound with suspension travel. Working together as a matched pair, they absorb road impacts, stabilise the vehicle body, and help maintain consistent tyre contact, steering accuracy, and ride comfort.
Coil springs weaken and sag over time due to constant load, mileage, and road conditions. Replacing only one spring can result in uneven ride height and compromised handling. Installing a pair restores correct suspension geometry, factory stance, and predictable driving dynamics.
Replace this part if you experience any of the following:
• Uneven or sagging front ride height
• Excessive body roll or unstable handling
• Cracks, corrosion, or visible spring fatigue
• Suspension overhaul, shock absorber replacement, or alignment work
• After significant mileage or heavy track/road use
