R0390S3 - SIDE STIFFENER L (IF18-3/CARBON)

This Urethane belt provides high durability under harsh conditions such as driving on dusty or dirty tracks, high temperatures or long finals. The belt teeth are hard and highly accurate offering good compatibility with the tooth profile and material of the pulleys helping to maintain excellent drive efficiency.

Mounted on the front portion of the upper deck to increase rigidity and steering response. Rigidity can be adjusted by using a combination of fixing screws.

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.

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.

In addition to the conventional 9, 10, and 11mm, the new 8mm is now available as a set with the necessary parts for installation!
 By using 8mm, the outer wheel has more angle allowing for a wider range of settings.
 R0259 Aluminum Servo Saver Set (top mount) is required.

IF18-3 setting parts

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

Revival of the plastic front body mounting plate that was a standard item on the INFINITY 1/8 racing first model and IF18. It subtly reduces the powerful front downforce from the body for smoother steering characteristics.

Spare part for R0390.
