Track-Focused FRP Chassis for the F109

RC racers seeking a tougher platform will appreciate the 3RACING F109-03/FRP Main Chassis and Upper Deck. Built from durable FRP, this upgrade increases chassis stiffness and refines handling to help you stay consistent lap after lap.

Advantages of FRP Construction

Fiber Reinforced Plastic gives a strong yet relatively lightweight structure, improving torsional rigidity without adding excessive mass. The result is a clearer steering feel and more predictable weight transfer through corners.

Set Up for Competitive Driving

Made for circuit use, this hop-up supports aggressive cornering and stable high-speed runs. The added rigidity helps maintain suspension geometry under load, which benefits drivers tuning for grip and pace.
