Information
Standard replacement coil spring - suitable for models equipped with a Standard chassis (option code: 029).
Sold individually – two springs are required per front axle.
We strongly recommend replacing coil springs in pairs.
Fits:
Porsche 991.1 Carrera 2 / Carrera 2S 2012 - 2016
* For cars with Standard chassis (option code: 029)
Diagram ref no 10
An front suspension coil spring designed to replicate the fit, function, and performance of the original Porsche M029 suspension spring.
This coil spring supports one front corner of the vehicle, managing suspension compression and rebound during braking, acceleration, and cornering. Tuned for the standard M029 chassis, it helps maintain proper ride height and a balanced blend of comfort and stability.
Installed between the lower control arm and the front strut assembly, the spring compresses and expands with suspension travel, absorbing road impacts and controlling body movement. Correct spring performance is essential for maintaining suspension geometry, steering precision, and consistent ride quality.
Standard suspension springs gradually weaken over time due to mileage, load, and road conditions. A worn spring can cause uneven ride height, reduced comfort, and altered handling. Replacing tired springs with new components restores factory-correct suspension balance and driving confidence.
When to replace:
• Front ride height appears uneven or sagging
• Noticeable reduction in ride comfort or stability
• Visible corrosion, cracks, or spring fatigue
• During front shock or strut replacement
• As part of a standard suspension refresh or alignment correction
