Swap in the Factory Pro O-TCP001 graphite main chassis on your Tamiya TRF421 to reduce weight and refine handling. The 2.25mm graphite construction offers a mix of stiffness and lightness that helps the car settle faster into corners. Cut precisely for TRF421 geometry, this chassis aids in achieving a neutral balance for consistent lap-to-lap feel.
Graphite is prized for delivering strong yet light chassis plates that improve traction and steering feedback. By trimming mass, you get snappier acceleration and more direct input response from the radio. The material also resists flex where you want rigidity, so tuning roll and bite becomes more predictable.
