A Quick Look at Suplex

Suplex information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts

Choosing the Right Fit for Your Porsche

Where Suplex is listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, side/position, and connector type where relevant.

  • Typical reasons to choose or replace these springs include sagging ride height, uneven stance side-to-side, corrosion damage, or restoring a factory feel during a suspension refresh.
  • Common symptoms of tired or failed springs include uneven ride height, knocking noises, broken coils (often at the bottom where corrosion starts), and poor ride quality, sometimes combined with worn dampers or pads.
  • Practical tip: many owners replace dampers, spring pads, and top mounts at the same time, and then have a full wheel alignment carried out once the new springs have settled.
  • After installation, expect a small amount of settling from new springs; recheck ride height and clearances after some mileage.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Suspension & Axle — Suspension and axle parts are typically replaced to restore handling, ride comfort, and braking stability where wear, age, or performance goals have affected the original feel.

  • After any significant suspension work, a professional alignment is strongly recommended.
  • Check for play, leaks, and bush wear before deciding which components to replace.

Coil Springs FRONT — Front coil springs are changed when the front ride height has sagged, a coil has cracked, or you are restoring suspension performance and maintaining the correct load rating for your Porsche.

  • Replace front springs in axle pairs and match them to suitable dampers, then check wheel alignment.
  • Even a small broken coil end can cause noise or alignment issues, so inspect carefully if symptoms are subtle.

Coil Springs REAR — Rear coil springs are replaced to correct rear sag, fix broken coils, and restore balance and stability so the car sits and behaves predictably in corners and under load.

  • Rear springs should also be replaced in pairs to keep handling consistent side-to-side.
  • Inspect spring seats and isolators; worn or damaged seats can cause noise and accelerate wear.

Spidan Coil Springs — Spidan coil springs are used as standard-style replacement items to restore correct ride height and load handling while maintaining predictable suspension behaviour with matching dampers.

  • Choose springs specified for standard ride height if you want to retain original behaviour.
  • Match the spring specification to the vehicle’s equipment and load rating to avoid an incorrect stance.
