Application: 2004-2011 Mazda RX-8
Note: Required  to use an ACT Flywheel

Taking a step up to a lighter flywheel will require a counterweight to maintain balance for improved engine response and acceleration. ACT flywheel counterweights are what you need with ACT Streetlite or Prolite flywheels for proper engine balance. These counterweights are available for your Mazda RX-8 application. Quality and performance are yours with ACT flywheel counterweights.
