Action Clutch aluminum lightweight flywheel for 2004–2011 Mazda RX-8 1.3L (13B-MSP) replaces the heavier stock flywheel to reduce rotating mass for sharper throttle response and improved shift feel. Engineered in the USA, the design pairs lightweight aluminum with a hardened steel ring gear and heat-treated friction surfaces, balancing reduced mass with strength and heat management for consistent clutch engagement.
