Strut Parts for Porsche Cayman 2016 GTS: Complete Guide to Replacement and Upgrade

If you own a 2016 Porsche Cayman GTS, you know that its suspension plays a major role in the car's sharp handling and ride comfort. Over time, struts can wear out, leading to reduced performance, uneven tire wear, or a bouncy ride. Whether you're replacing worn components or upgrading for better track performance, choosing the right strut parts matters. This guide covers the essential strut parts for the 2016 Cayman GTS, what to look for, and how to make an informed decision.

Understanding the 2016 Porsche Cayman GTS Suspension

The Cayman GTS comes with Porsche Active Suspension Management (PASM) as standard, which automatically adjusts damping based on driving conditions. This system uses electronically controlled dampers (struts) that are integrated into the front and rear suspension. Replacing or upgrading struts on a PASM-equipped car requires parts that are compatible with the electronic system, unless you plan to delete PASM.

Front and Rear Strut Assembly Differences

The front strut assembly on the 2016 Cayman GTS includes the strut (damper), coil spring, top mount, and sometimes a bearing plate. The rear uses a separate spring and damper setup (not a true strut in some definitions), but for practical purposes, the damper is the critical component. Many aftermarket options package these as complete assemblies for easier installation.

Key Strut Parts for Replacement

When shopping for strut parts, you'll encounter several components that may need replacement together:

1. Strut / Damper

The damper is the core part that controls motion. For the 2016 Cayman GTS, you have three primary options:

• Original Equipment (OE) PASM struts – Direct fit, maintain the factory adaptive damping. Expensive but ensure proper integration.
• OE replacement (non-PASM) struts – Some owners choose to delete PASM by installing standard shocks, often with a manual adjustment or fixed damping. Requires coding or resistor bypass to avoid warning lights.
• Aftermarket performance struts – Brands like Bilstein, KW, or Ohlins offer coilover kits that replace the entire strut/spring assembly. Many are designed to work with PASM (e.g., Bilstein B6 PASM) or delete it (KW V3).

2. Coil Springs

If you replace struts, consider new coil springs unless your current ones are in good condition. Springs can sag over time, affecting ride height and handling. OEM spring rates are tuned for the GTS's balance. Aftermarket springs (e.g., H&R, Eibach) lower the car and stiffen the ride, but may require corresponding damper changes.

3. Strut Mounts and Bearings

Front strut mounts (top hats) include a bearing that allows the strut to rotate with steering. Worn mounts cause clunking noises. Always replace these with new struts. Rear mounts are also available, though less commonly worn.

4. Dust Boots and Bump Stops

These protect the damper rod from dirt and limit compression travel. Most aftermarket strut assemblies include them, but when buying individual dampers, order separately.

5. Related Hardware

Bolts, nuts, and washers are often replaced to ensure proper torque. Some aftermarket kits include new hardware; for OE parts, you may need to order separately.

OEM vs Aftermarket: What to Choose

Your choice depends on your goals:

• Daily driving / comfort: Stick with OE or OE-equivalent struts like Sachs (who builds for Porsche). Cost is higher but reliability is proven.
• Track / performance: Consider coilover kits from Bilstein B16, KW Clubsport, or Ohlins Road & Track. These offer adjustable damping and ride height but may compromise comfort.
• Budget replacement: OE replacement struts from brands like Monroe or KYB are available, but use caution with PASM compatibility. Most non-PASM options require a bypass module.

Compatibility Notes for 2016 Cayman GTS

The 2016 GTS uses the 981 chassis (2013-2016). Parts for the 981 Cayman S or base may fit, but the GTS has specific damping calibration. Always verify part numbers with your VIN. PASM struts are coded to the car; if you replace with non-PASM, the PASM button will not function, and you may see a warning light without a delete kit.

Installation Considerations

Replacing struts on a Cayman GTS is not a simple driveway job for most. The front struts require spring compressors and careful handling of the electronic connector. Rear dampers are easier but still involve interior trim removal and careful torque specs. Professional installation is recommended unless you have experience with Porsche suspension work. An alignment is mandatory after any strut replacement.

Recommended Brands and Part Numbers

While exact part numbers change, here are reliable options:

• OE PASM Front Strut: Porsche part 981-343-048-03 (left) and 981-343-047-03 (right). Verify with dealer.
• Bilstein B6 PASM: Direct fit adaptive damper, maintains PASM function.
• Bilstein B8 PASM: Lowering damper for use with sport springs.
• KW V3 Coilover: Full kit with adjustable damping and height, typically deletes PASM.
• Sachs OEM replacement: Often original equipment; Sachs part numbers available from suppliers.

Signs Your Struts Need Replacement

• Excessive bouncing after a dip or over bumps.
• Nose dive under braking.
• Uneven tire wear (cupping or scalloping).
• Fluid leaks on the strut body.
• Clunking or knocking from suspension.
• The PASM warning light appears (could indicate strut failure).

Final Recommendation

For most Cayman GTS owners, the smartest choice is to replace worn struts with Bilstein B6 PASM units. They maintain the adaptive damping, improve handling over worn OE struts, and cost less than dealer parts. If you want a sportier setup and are willing to lose PASM, a KW V3 coilover kit transforms the car's behavior. Always align your choice with your driving needs and budget, and have a qualified Porsche specialist perform the installation. Regular inspection of your suspension will keep your Cayman GTS performing at its best for years to come.
