Thank you. You have rated this product.

The stock Mazda Miata flywheels are heavy parts designed for optimum street driveability by soaking up some of the power from the engine and putting it in storage in the form of inertia. Although this may be important for transporting the groceries, this driveability comes at the expense of engine response and acceleration.

Light weight Miata flywheels keep less inertia in storage but the lighter rotating mass provides significantly improved engine response and acceleration characteristics.

XACT Miata flywheels are certified by ACT to meet SFI Spec. 1.1. This makes the XACT Miata Flywheel legal for competition when SFI Spec. 1.1 is required or recommended. The XACT Miata flywheel comes complete with official SFI sticker and serial number as required for certification.

ACT offers what performance enthusiasts need: the benefits of a premium quality light weight aluminum Miata flywheel at a MORE affordable price...in steel.

ACT currently manufactures the XACT steel Miata flywheel in two versions, ProLite (9 Pounds) for road racing and autocross applications and very quick throttle response, and slightly heavier StreetLite (13 Pounds) for street and drag racing vehicles which may require more inertia. Both ProLite 600255 and StreetLite 600290 Miata flywheels are precision made from Chrome-moly forgings and feature an induction hardened integral ring gear. All ProLite and StreetLite flywheels are CNC machined, heat treated for strength and precision balanced. Substantial material is left behind the clutch surface area for better heat dissipation and durability while weight savings is made where it matters the most for reduced inertia.

I have to say that your website is one of the cleanest, most functional and easy to use. There are a lot of independent part sellers that have horrible websites and it was a joy to use yours and even explore the customer car gallery and the good win build page. Thank you for a great experience.

Brian, Thank you!!! We last spoke in November about some upgrades for my 2011 MX5 soft top. It has finally warmed up in NE Ohio and two relaxed weekends of wrenching on my car were well worth the effort. Installation of the RoadsterSport ceramic coated street header was straight forward and took under 8 hours, including a 40 minute test drive and cleanup of the garage! Combined with the RoadsterSport Q exhaust, the sound is fantastic and the increased torque, horsepower and performance make it a blast to drive. The addition of the Cobalt shock tower brace, Racing Beat sway bars, ILM front power train and X braces really enhanced the ride - minimal body roll, comfortable and very responsive. Your recommendations really helped transform the car from great to fantastic. Your research, product development and candid recommendations make you a standout in the industry. My only questions are - what's next on my list .... And how soon will my wife want the same upgrades on her 2012 PRHT ... Again, thank you!!! Charles G
