If your Porsche Boxster or Cayman is showing signs of a failing clutch, the genuine OEM replacement is part number 98611691102. This clutch kit is the exact assembly used during production, ensuring a precise fit and reliable performance. Before purchasing any aftermarket alternatives, here is what you need to know about this specific part, its compatibility, installation, and overall value.
What Is Porsche Clutch Kit Part 98611691102?
Part 98611691102 is a complete clutch kit manufactured by Porsche for the 986 generation Boxster (1997–2004) and the early 987 generation Cayman (2005). The kit includes the clutch disc, pressure plate, release bearing, pilot bearing, and alignment tool. All components are sourced from the same suppliers that Porsche uses for original assembly, so the quality matches factory specifications exactly.
Compatibility
This clutch kit is designed for:
- Porsche Boxster (986) – All model years 1997 through 2004
- Porsche Boxster S (986) – All model years 2000 through 2004
- Porsche Cayman (987) – Model year 2005 (early production only; later Cayman models use a different clutch)
It is also compatible with the Carrera GT? No, it is not. This kit is strictly for the flat-6 engines found in the 986 Boxster and early 987 Cayman. Always double-check your vehicle's VIN to confirm fitment, as minor variations exist between manual transmissions.
Signs That Your Clutch Needs Replacing
Before ordering the 98611691102 kit, symptom recognition helps confirm the need. Common indicators include:
- Slipping – Engine revs increase without a corresponding gain in speed.
- Chatter or vibration – Feeling when engaging the clutch.
- Difficulty shifting – Gears grind or resist engagement.
- Pedal feel changes – Clutch pedal becomes stiff, soft, or grabs too high or too low.
- Burning smell – A burnt odor, especially after aggressive starts.
If you notice any of these, the clutch components are likely worn beyond safe limits. Prompt replacement prevents damage to the flywheel and transmission.
What Is Included in the Kit?
The genuine Porsche clutch kit 98611691102 contains:
| Component | Quantity | |-----------|----------| | Clutch disc | 1 | | Pressure plate | 1 | | Release bearing | 1 | | Pilot bearing | 1 | | Clutch alignment tool | 1 | | Spring retainer clips | 2 (sometimes) |
All components are pre-balanced and ready for installation. The disc and pressure plate feature organic friction material for smooth engagement and long service life. The release bearing is a sealed unit that does not require additional greasing.
Differences from Aftermarket Kits
Many aftermarket clutch kits for the 986 Boxster are available at lower prices, but they differ in several ways:
- Material quality – Aftermarket discs may use cheaper facings that wear faster or grab unevenly.
- Balance – Genuine Porsche kits are balanced to tighter tolerances, reducing vibration.
- Fitment – Aftermarket pressure plates sometimes require additional shimming or cause clutch drag.
- Warranty – The genuine kit comes with Porsche's warranty when installed by a certified shop.
For daily driving and occasional spirited use, the OEM kit provides predictable performance and longevity. If you are building a track car or need higher torque capacity, aftermarket performance kits (e.g., Sachs or SPEC) may be better – but they require careful research for compatibility.
Installation Overview
Installing clutch kit 98611691102 is a major job that typically requires 6–10 hours of labor. Steps include:
- Disconnect battery and remove exhaust – The mid-engine layout requires dropping the muffler and heat shields.
- Remove transmission – The gearbox must be separated from the engine and lowered out.
- Replace clutch components – Remove old disc, pressure plate, and bearings. Install new pilot bearing, then align the disc with the tool before bolting the pressure plate.
- Reinstall transmission – Torque bolts to specification.
- Reconnect everything – Exhaust, driveshaft cables, and battery.
Important: The flywheel should be inspected or resurfaced if there is scoring or hot spots. Some technicians recommend replacing the flywheel with a new or dual-mass unit at the same time, as it affects clutch behavior and pedal feel.
Because access is tight in the engine bay, professional installation is recommended unless you have experience with Porsche drivetrains. Using a factory workshop manual ensures torque values and alignment procedures are correct.
Cost Considerations
The price of part 98611691102 varies by dealer but generally ranges between $300 and $500 for the kit alone. Labor costs for installation at an independent shop can add $800 to $1,200, depending on your area. Dealership labor will be higher. Total replacement cost is typically $1,200–$1,700.
While aftermarket kits can save $100–$200 upfront, the risk of premature wear or poor fitment may offset any savings. The genuine kit is a safe choice for owners who plan to keep the car for several years and want predictable performance.
Conclusion and Recommendation
For most Porsche Boxster and early Cayman owners, the genuine clutch kit part 98611691102 is the best option for restoring factory clutch feel and reliability. It includes all necessary components, fits perfectly, and comes from original manufacturing sources. If you are a DIY mechanic with moderate experience, this kit can be installed successfully with proper tools and patience. For others, investing in professional installation is worth the peace of mind.
A few final tips:
- Always replace the pilot bearing and release bearing – they are included.
- Consider replacing the rear main seal (RMS) while the transmission is out – it is a common leak point.
- Check the condition of the flywheel and replace if necessary.
- Buy the clutch kit from an authorized Porsche dealer or a reputable OEM parts supplier to avoid counterfeits.
The genuine Porsche clutch kit 98611691102 delivers the same quality and longevity as the original clutch that came with your car. If you are ready to fix that slipping or noisy clutch, this is the part to get.
