Competition Clutch Ultra Lightweight Steel Flywheel for 1999 Mazda Miata MX5

The Competition Clutch Ultra Lightweight Steel Flywheel is recommended for forced induction and/or track and rally racing applications. Although this flywheel can work with most performance and stock clutch assemblies, we recommend a Competition Clutch performance clutch kit for best results.

Key Features:

• One piece ring gear for high durability.
• Weight varies from 8 lbs. to 10 lbs., depending on application.
• Stamped with a 4140 plate with 2000 tons pressure at 1260 degrees.
• Well suited for Stage 3 and up clutch kit applications.
• CNC machined and balanced to OEM specifications.
• Reduced mass of the flywheel increases acceleration of your Mazda Miata MX5.
• Meets and exceeds SFI 1.5 specifications.
• 90 day limited warranty.

Note: If you plan on using your Mazda Miata MX5 for normal street use or drag racing, you may prefer the regular Competition Clutch Lightweight Steel flywheel. For straight-line acceleration, a higher moment of inertia is more desirable because it keeps the engine from slowing itself down too quickly. The Ultra Lightweight Steel Flywheel is made for road racing, where a low moment of rotational inertia will lead to better lap times.
