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

This set of Φ8.5mm titanium ball screws is for use with the IF18-2. (Set includes 4 normal size and 2 long size) For smooth and light driving.

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)

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.

By installing this Front Carbon Wheel Plate on the front knuckle, turbulent air generated in the front wheels during driving is cleaned up offering more stable driving characteristics. The effect is especially noticeable on high-speed circuits.

Connects the brake mount L/R to the rear lower bulk, This part increases the rigidity of the rear area. It improves the rear grip.

Lightweight and rigid flat head screw made of titanium, with the optimum length for installation of 2-speed spur gears for more secure tightening.

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.

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.

High-precision machined aluminum spring guide for improved steering response and rear traction. Hard coating is applied to ensure durability of the contact area with the spring and to maintain good condition for a long period of time.
