2 Duro medium tire 4.5-5"SL56

The version R 25-31 is the evolution of the steering column for short wheelbase chassis (mini). The dimensions are adjusted to provide a leverage adapted to the force of young drivers while maintaining a high level reactivity.

• Specific geometry: The code R 25-31 Indicates the spacing and height of the anchor points of the rods. This configuration helps keep an incisive front train without being too physical for a child.

• Quality of construction: Same as adult models, it uses a chrome-molybdenum steel capable of collecting the constraints of the competition while remaining light.

• Modularity: It usually has two mounting positions for the rods to adjust the ACKERMANN effect according to the track conditions (dry or rain).

The plaque R 35-40 Refers to the center distance ratings for the mounting holes for steering ball joints. It is this component that transforms your steering wheel movement into a steering angle.

• R 35-40 code: These figures correspond to the positions of the holes (in millimeters) relative to the central axis of the column. They determine the turning speed and the necessary force behind the wheel.

• ACKERMANN effect: By proposing several anchor points, this plate adjusts the angle difference between the inner and outdoor wheel.

  • Interior holes: Directorate more direct and more "physical".

  • Exterior holes: Softer and more progressive direction.
