The Tamiya 47332 - FS-12FZ/FN Light Aluminum Flywheel is a concise performance upgrade for TG-10 Mk2 owners who want crisper engine behaviour. Built from light metal, it trims rotational weight while keeping structural strength for regular track sessions.
Matched to FS-12FZ/FN engines, this flywheel lowers inertia to help the engine spool faster and respond to throttle adjustments with less lag. The change benefits both acceleration and mid corner throttle control.
Designed for TG-10 Mk2 fitment, the flywheel aligns with the chassis mounting points for a clean swap. Accurate machining ensures it seats correctly without extra shims or modifications.
