R0389 - MAIN SHAFT STIFFENER (IF18-3/CARBON)

Rear universal swing shaft is for use with widened rear track width or high grip conditions. Difference in length from standard R0116-54 (54mm-->56mm)

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.

Made from a 4mm thick carbon plate for high rigidity and is ultra-lightweight. By transmitting all of the downforce at high speeds to the rear tires, it achieves overwhelming rear traction!

New 0.8 module spur gear designed for high precision, high strength, and high durability. Gear specifications have been redesigned to provide uniform backlash for all tooth number combinations. The tooth width of the 2nd gear spur gear (R0409T56-T58) has been increased by approximately 12% to achieve even higher strength and durability. *Cannot be used in combination with conventional 0.8 module spur gears (R0247-60-62 and R0248-56-58) to prevent gear breakage. *Pinion gears for IF18-3 (R0384T18, R0384T19, R0385T23, R0385T24) must be used.

The use of lightweight titanium screws inside the two-speed unit contributes to improved engine pickup. The screw head is shaped to achieve the lightest weight possible.

Option part for IF18. This aluminum body mount spacer is to be used together with the optional 1 piece carbon mounting plate (R0198) Offers extra body post stability and is available in both silver and red.

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).

Maintenance and adjustability is greatly improved with this servo saver arm by mounting to the steering rod upper side.  Also, by changing and optimizing the arm length of the servo saver, the steering response will be higher than before.
