R0392 - CHASSIS STIFFENER F (IF18-3/CARBON)

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.

An all new front one way set featuring larger one way bearings for improved durability. The timing of the drive transmission to the front tires has also been changed resulting in milder and more easy to drive characteristics. The overall weight has been reduced to 24g, 4g lighter than the original.

This clutch spring is made of a material that keeps the IF18 clutch in great condition for longer. Perfect to help utilise maximum engine power.

A special manufacturing process ensures long life and consistent performance.
As the overall length is approximately 11mm,
please use it together with R0413 CLUTCH SPRING HOLDER (for R0412).

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.

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.

Spring holder for R0412 long life clutch spring (long type/11mm).
 The surface is silver to distinguish it from the R0251-06 clutch spring holder (black).

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.

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)

To change ackerman angle (more increase angle of outside front tyre)

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!
