Factory Team RC8B3 4-shoe steel flywheel
Team Associated now offer a new optional Factory Team 4-shoe steel flywheel for the RC8B3. A direct replacement for the standard aluminium version (12 grams), the steel flywheel (36 grams) is heavier and therefore increases the overall rotating mass of the clutch assembly. This offers a more stable engine idle and a smoother bottom end throttle feel.
