These bolts are responsible for safely securing the flywheel to the crankshaft. Proper bolt stretch and friction prevent loosening, fretting, or flywheel run-out that could lead to clutch or starter damage.

Over time, flywheel bolts can stretch, corrode, or lose their strength due to heat and torque cycling. Replacing them ensures consistent preload and drivetrain safety.

Replace the flywheel bolts when:
• Performing a clutch or flywheel replacement (most Porsche bolts are single-use torque-to-yield).
• Bolts show signs of corrosion, thread damage, or head wear.
• The factory service procedure specifies new bolts for reassembly.

Installing a complete new set of 9 ensures even torque distribution, secure fastening, and dependable long-term performance.
