What is the main benefit of a steel flywheel over an aluminum one?

Steel flywheels are generally more durable and better at dissipating heat, which can be beneficial for longevity, especially in daily driving scenarios. They also tend to have a more consistent feel during clutch engagement compared to lighter aluminum options.

Does this flywheel come with a new pilot bearing?

This SPEC steel flywheel (Part# SP87S-9) is sold as the flywheel only. It does not include a pilot bearing or any other clutch components. It is recommended to replace the pilot bearing when installing a new flywheel.

What other parts should I consider replacing when installing a new flywheel?

When replacing your flywheel, it's a good time to also replace the clutch disc, pressure plate, and release bearing. Inspecting and replacing the pilot bearing and rear main seal is also highly recommended as they are easily accessible during this job.

About this part

Product Details

If you're rebuilding the clutch system on your 2009-2012 Porsche Boxster or Cayman with the 2.9L engine, a new flywheel is a critical component. This steel flywheel from SPEC is designed to be a direct replacement for your original part, ensuring proper engagement with your clutch assembly. A well-functioning flywheel is essential for smooth starts from a stop and for transferring power efficiently from the engine to the transmission.

This SPEC flywheel is constructed from solid steel, a durable material chosen for its strength and ability to handle the heat and stress of regular driving. Unlike lighter aluminum flywheels, steel offers a more substantial feel and can be a good choice if you're looking for a reliable, long-lasting replacement without significantly altering the engine's rev characteristics. It's designed to meet the specific needs of the 2.9L Boxster and Cayman, meaning it bolts up directly without modifications, making installation straightforward for a mechanic.

When replacing your clutch, it's always a good idea to inspect your pilot bearing and rear main seal, as these are easily accessible with the flywheel removed. This SPEC flywheel is built to last and will help ensure your clutch system performs as it should for many miles to come.
