Product Description:
The BBi Autosport Porsche 997 Turbo Clutch Slave Cylinder Conversion Kit is a direct replacement part that eliminates the problematic factory power-assist system for improved reliability and pedal feedback.
The factory power-assisted clutch system has always been the Achilles heel for the Porsche 997 Turbo. Utilizing the power steering system to help reduce the force needed to depress the clutch pedal, it is a flawed design that delivers a mushy pedal feel with poor feedback, and is highly prone to failure.
Unlike other kits, the BBi Autosport kit is designed be used with OEM clutch master cylinder, hose, and spring pack. This eliminates the need for additional parts, making our kit a complete plug and play solution.
The other kits on the market simply adapts factory 996 GT2 parts with aftermarket brackets and caps off the power steering pump with plugs. The BBi Autosport kit's proprietary design does not plug the power steering pump because the plugs can fail. Instead, the power steering fluid is routed through the unit to simulate the factory system.
With the failure of the factory system inevitable, this is a must upgrade for the 996 and 997 Turbo to achieve the excellent pedal feedback and reliability like that of the Porsche 997 GT2 and GT3 without compromising drivability.
Features:
• Eliminates the problematic OEM power-assisted clutch slave cylinder for improved reliability
• Significantly improves the clutch feel and engagement
• Designed to be slightly softer than the factory 996 GT2 conversion kit for excellent drivability
• Proprietary plug and play design
• Retains clutch master cylinder, hose, and spring pack
• Requires less installation time than other slave cylinder conversion kits
• Does not adversely affect clutch life
• Precision CNC machined and hard anodized aluminum construction
• Hard anodized 7075 aluminum piston
• Designed for Porsche 996 and 997 Turbo
This slave cylinder works best with an upgraded pedal spring
OEM Pentosin fluid must be fully flushed out and replaced with DOT4 Brake fluid.
The seals will fail if this procedure is not carried out

Porsche Performance Clutches & Flywheels - Drivetrain Power Transfer Upgrades
Clutches and Flywheels are essential drivetrain components responsible for transferring engine power to the gearbox while managing torque, engagement, and rotational stability. In tuned or high-output Porsche engines, upgraded clutch and flywheel solutions are critical to handle increased power levels while maintaining drivability and reliability.
Available from Design911, this range of Porsche performance clutches and flywheels is engineered to improve torque capacity, engagement control, and durability for road, track, and motorsport applications.
What Do Clutches & Flywheels Do?
Clutches and flywheels manage power transfer between the engine and transmission.
Core Functions:
Transmit
engine torque to the gearbox.
Allow
smooth gear changes and engagement.
Manage
rotational mass and engine response.
Reduce
drivetrain shock and vibration.
Support
reliable operation under load.
Proper clutch and flywheel performance is essential for safe and efficient power delivery.
Why Do Clutches & Flywheels Fail?
Standard factory clutches and flywheels are designed for
stock power output and comfort. Failures commonly occur due to:
- Increased torque from engine tuning or modifications.
- Excessive heat from aggressive driving or track use.
- Friction material wear over time.
- Dual-mass flywheel degradation or failure.
- Clutch slip caused by insufficient clamping force.
Failing components can result in slipping, vibration, poor engagement, and drivetrain damage.
Why Upgrade to Performance Clutches & Flywheels?
Performance clutch and flywheel upgrades are designed to handle higher torque and heat.
Upgrade Benefits:
- Increased torque capacity for tuned engines.
- Improved engagement and pedal feel.
- Reduced rotational mass for faster engine response.
- Enhanced heat resistance for track use.
- Improved reliability under high load conditions.
Upgrading ensures the drivetrain can safely manage increased performance demands.
Highlights
- Porsche performance clutches and flywheels
- Increased torque handling and durability
- Designed for tuned, track, and high-output engines
- Improved engagement and response
- Essential upgrade for performance builds
