Not only has rigidity been increased by using A7075, but the pivot height has been raised by 2mm compared to the standard part R300B/300H, providing more responsive steering and changing the camber change rate. To ensure clearance inside the wheel, the ball has been downsized from 8.5 to 8.0mm and the screw cap from 10 to 9mm and tilted by 10°. A specially prepared 8mm titanium ball is included to ensure proper steering angle. The main body is hard anodized.
By moving the 3x11.8mm pin position of the universal shaft through 90 degrees this allows for a more free drive transmission at high RPM and a smoother suspension movement under high load, overall offering an increased steering feel.
The drivetrain of the IF18-3 has been lightened to improve response during acceleration and deceleration. The weight is approximately 7g lighter than the 8mm shaft.
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.
Weight has been reduced by F:0.3g R:0.5g, removing this unnecessary material has improved rotational balance. Reduced clearance in the thrust direction helps maintain wheel stability during running.
New part that improves response when entering/exiting corners. This pin position is 0.5mm higher and 1mm wider than the standard R0230-IN suspension pin position.
