R0394S9 - 6x13 BEARING BUSH (IF18-3)

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 material and coating have been updated to significantly improve crash resistance and durability compared to the standard items. The shaft is highly durable and resistant to scratches even after long periods of use.

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.

By greatly increasing rigidity in the rear section of the  chassis, the car's turning ability is noticeably reduced, making it easier to manoeuvre on extremely low-grip surfaces or high-grip surfaces where traction roll could be a problem.
