What is the main benefit of an aluminum flywheel?

An aluminum flywheel has significantly less rotational mass than a stock cast-iron flywheel. This means your engine can spin up faster, leading to quicker acceleration and a more responsive feel when you press the gas pedal.

Does this flywheel come with new bolts?

This listing is for the aluminum flywheel only. It is highly recommended to purchase new flywheel bolts, as they are often torque-to-yield and should not be reused.

What kind of clutch disc should I use with this flywheel?

This SPEC aluminum flywheel is designed to work with most standard clutch disc materials. Ensure the clutch disc you choose is compatible with your Mazda 3's transmission and intended use.

Product Details

This listing is for one SPEC aluminum flywheel, part number SZ35A-3, designed for the 2012-2018 Mazda 3 with the 2.0L Skyactiv-G engine. This flywheel is a direct replacement for your factory unit, but it offers a significant weight reduction that can make a noticeable difference in how your car accelerates.

Crafted from high-grade aluminum, this flywheel weighs considerably less than a stock cast-iron unit. This reduced rotational mass means the engine doesn't have to work as hard to spin it up, leading to quicker throttle response and a more eager feel when you step on the gas. It's a popular choice for drivers looking to improve their car's performance without going for a full clutch kit. While it's a lighter component, SPEC builds these to handle the demands of daily driving and spirited use. The friction surface is designed to mate well with most clutch disc materials, ensuring smooth engagement.

When installing this flywheel, it's important to follow the manufacturer's recommended torque specifications for the flywheel bolts and to ensure the mating surface of your clutch disc is clean. You'll also want to consider replacing your clutch bolts, as they are often single-use. This flywheel is a solid option for anyone wanting to unlock a bit more responsiveness from their Mazda 3's drivetrain.
