Fidanza 04-07 Mazda 3 (Non 07 MazdaSpeed3)/06-07 Mazda 5 Aluminum Flywheel

If you're looking to get more out of your 2004-2009 Mazda 3 (excluding the 2007 Mazdaspeed3) or your 2006-2007 Mazda 5, this aluminum flywheel from Fidanza is a solid option. It's designed to replace your stock flywheel, which is typically much heavier, and offers a noticeable improvement in how quickly your engine can rev up.

This Fidanza flywheel is made from a billet 6061 T6 or 2024 T4 aluminum body, making it 40-60% lighter than the original part. This reduction in weight, known as lower MOI (Moment of Inertia), means your engine can accelerate faster, giving you a more responsive feel when you hit the gas. The friction plate is heat-treated for better grip and longer life, and it's a replaceable part, which is a nice touch. Fidanza also uses military-spec fasteners to ensure everything stays reliably in place, and the ring gear is made of hardened 1050 steel, which is also replaceable.

When installing this, you'll find it's a bolt-on replacement for most applications, and it comes with stepped dowels to help with alignment. Keep in mind that this part is designed for performance and weight savings, so you'll likely notice a difference in how the engine responds, especially during quicker acceleration.
