- The new shape of the carbon lower and upper decks has moved the motor position 22.7mm forward compared to the previous model, the TRF420X.
- The center shaft has been placed in the center of the chassis, and the drive belts are equal length front and rear.
-The front and rear pulleys also have a new shape.
-This change has reduced pitching when operating the throttle, resulting in a more stable drive.
-The front and rear bulkheads have also been reshaped to lower the center of gravity, and new USBB (ultra short big bore) dampers are mounted with aluminum stays.
- Spacers are now available for fine angle adjustments.
-The suspension uses high-rigidity A-arms on the upper and lower sides.
-The lower arms are the same for the front and rear, and the longer span makes the roll posture when cornering even more linear, improving stability when controlling the car.
