The 3Racing F109 Graphite Rear Motor Mount Plate, model F109-U13/E/WO, provides a targeted stiffness increase to the F109 chassis rear. Machining and material selection deliver a lightweight but rigid mounting surface that aids in tuning rear roll and traction response during competitive runs.
Graphite offers improved rigidity to reduce chassis flex at the motor mount interface, translating setup changes more directly to on-track behaviour. This plate helps racers refine weight transfer and rear-end predictability without large mass penalties.
Designed for bolt-on integration with standard F109 mounting points, the plate requires routine verification of screw torque and alignment. When combined with other tuning parts, it forms part of a coherent upgrade path to optimise rear traction and steering feedback.
