Engineered for the F109 platform, the 3Racing Plastic Upgrade Part A provides targeted stiffness where chassis flex impacts handling. The component uses a durable plastic compound chosen to balance strength, weight, and resistance to fatigue during repeated impacts.
Install the 3Racing F109-01 Plastic Upgrade Part A as part of a measured setup routine. Small changes in chassis rigidity can alter steering progression and mid-corner balance, so recheck toe, camber, and roll centre after fitting.
