A brass battery plate that concentrates the weight in the center of the car body and increases the chassis rigidity achieves higher driving stability. In particular, it is easy to control on a high-grip road surface and prevents traction roll.
Lightweight and strong 64 titanium material is precision-machined to increase the overall length and ensure rigidity even when the rear upper arm is set at its longest setting. (Use with R0343 is recommended)
Uses a softer material than the standard R0303-01. Increases crash resistance. The steering response is also mild.
(M2x8mm Flat Head Screw is not included.)
Making the material harder than the standard kit version the flex of the arm is reduced and rear traction is increased. Offering increased consistency in high grip and high temperature conditions.
A new lineup of pinion gears for the IF18-2 with a hard coating on 7075 aluminium material. Offered in all teeth sizes to fine tune gear ratio according to the engine and track layout.
A carbon stiffener that can be added to the front lower arm to increase rigidity. Increased steering response and higher cornering speeds can be achieved in certain conditions. Its also possible to adjust the flex and rigidity by the number of mounting screws used.
A new aluminium servo horn designed specifically for IF18. 23T specification for servos made by Sanwa and KO. By making the shape of the arm offset it is possible to achieve the maximum steering angle with a linear steering operation. Use in combination with R0259 Aluminium servo saver (up side).
