*NOTE: This clutch assembly is compatible only with 991 GT3 RS models manufactured on or before January 28, 2018. For vehicles produced from January 29, 2018 onward, a different part number is required. 

Offering an alternative to the Genuine Porsche assembly, it helps restore smooth clutch engagement and efficient power transfer when the original unit becomes worn or damaged.

Compatibility depends on the transmission code and production date. Not all PDK variants use the same clutch assembly. Confirm fitment against the vehicle VIN and Porsche parts catalogue before ordering.

What Does It Do?

The PDK clutch assembly controls the transfer of engine power into the gearbox.

Unlike a conventional manual clutch, the PDK transmission uses two electronically controlled clutches to operate alternating gear sets, allowing the next gear to be prepared before the current gear is disengaged.

This provides fast gear changes with minimal interruption to power delivery.

Why Is It Important?

A properly functioning clutch assembly is essential for smooth acceleration, reliable gear engagement and consistent transmission performance.

A worn or faulty assembly may cause:

  • Jerking or shuddering when pulling away
  • Clutch slipping during acceleration
  • Delayed engagement of Drive or Reverse
  • Harsh or inconsistent gear changes
  • PDK gearbox warning messages

Why Does It Fail?

Possible causes include:

  • Normal clutch friction wear
  • Repeated high-load driving
  • Excessive gearbox temperatures
  • Contaminated or deteriorated transmission oil
  • Internal mechanical damage

When Should It Be Replaced?

Replacement may be required when diagnostic testing identifies excessive clutch wear, slipping or internal damage.

The assembly should also be inspected during major PDK gearbox repairs or transmission rebuilding.

Checks & Installation

Inspect the gearbox, clutch housing and related seals before installation.

Fitting requires specialist PDK transmission knowledge and suitable workshop equipment. Gearbox oil servicing, diagnostic checks and clutch adaptation procedures may be necessary after replacement.

Key Features

  • Supports smooth clutch engagement and power transfer
  • Suitable for selected Boxster, Cayman and 911 models
  • Replacement for worn or damaged clutch assemblies
  • Intended for specialist gearbox repairs

Porsche PDK Clutch Assemblies & Dual-Clutch Transmission Parts

Porsche PDK transmissions use a dual-clutch system to deliver rapid gear changes and smooth power transfer. Over time, clutch wear or internal damage can affect transmission performance and driving comfort.

About Clutch Friction Plate

Porsche Clutch Friction Plates | Precision Grip for Smooth Power Delivery

Clutch friction plates are the heart of your Porsche’s clutch system, responsible for transferring engine torque smoothly to the transmission. These high-performance discs sit between the pressure plate and flywheel, creating the essential friction that enables seamless engagement and power delivery through the drivetrain.

At Design911, we supply premium clutch friction plates and disc kits designed to match or surpass original engineering standards. Crafted from advanced friction materials such as organic composites, ceramic, or Kevlar blends, each plate provides superior bite, heat resistance, and longevity — ensuring reliable performance for both road and track applications.

Whether you’re restoring a classic 911, replacing worn components in a Cayman, or upgrading a Boxster for improved response, our clutch friction plates deliver precision engagement, smooth shifting, and enhanced durability.

What Do Clutch Friction Plates Do?

Clutch friction plates are the critical link between your engine and gearbox, transmitting power whenever the clutch engages.

Core Functions:

  • Provide the friction surface between flywheel and pressure plate.
  • Transfer engine torque efficiently to the transmission.
  • Enable smooth gear shifts by controlling engagement speed.
  • Maintain consistent performance under varying heat and load.

Without properly functioning friction plates, your Porsche’s clutch may slip, lose bite, or engage unpredictably — affecting acceleration, fuel efficiency, and drivability.

Why Do Clutch Friction Plates Fail or Wear Out?

Over time, clutch friction plates endure extreme temperatures, torque, and frictional stress. Continuous engagement and disengagement cause gradual surface wear, reducing grip and performance.

Common Causes of Failure Include:

  • Excessive slipping or “riding” the clutch pedal.
  • Contamination from oil or hydraulic fluid leaks.
  • Heat glazing or burning from aggressive driving.
  • Material wear due to age or poor lubrication.
  • Uneven pressure plate contact or warped flywheel surfaces.

As the friction material wears thin, the clutch begins to slip, causing poor acceleration, increased revs without movement, or a burning smell — clear signs it’s time for replacement.

Why Replace or Upgrade Your Porsche Clutch Friction Plates?

Replacing worn friction plates ensures optimal clutch engagement, improved grip, and a more responsive driving experience. Upgrading to high-performance friction materials enhances durability and torque handling — especially for tuned or track-driven Porsches.

Key Benefits:

  • Restores efficient torque transfer and smooth engagement.
  • Prevents clutch slippage and performance loss.
  • Reduces heat build-up and wear under load.
  • Improves pedal feel and shift precision.
  • Available in multiple friction materials for different driving styles.
  • Perfect for maintenance, performance, or complete clutch rebuilds.

It’s strongly recommended to replace the friction plate during any clutch service or flywheel resurfacing to maintain balanced, long-term performance.

Highlights

  • Premium Porsche clutch friction plates for road or track use.
  • Engineered for consistent torque transfer and smooth operation.
  • Made from high-friction, heat-resistant materials.
  • Designed to match Porsche specifications for fit and performance.
  • Available for 911, Boxster, Cayman, and other Porsche models.
  • Essential for clutch replacement, rebuilds, or performance upgrades.
