R0390 - SIDE STIFFENER SET (IF18-3/CARBON)

Repair parts for R0400

Repair parts for R0394

New stabilizer stopper for IF18-3 front stabilizer.
By making the contact surface with the bearing spherical, smoother movement of the stabilizer is acheived.
Durability has also been greatly improved by using steel.
Available in 2.3, 2.5, and 2.7mm.

Compatible stabilizers
Stopper 2.3mm (R0382S23): 2.0mm, 2.1mm, 2.2mm, 2.3mm
Stopper 2.5mm (R0382S25): 2.4mm, 2.5mm
Stopper 2.7mm (R0382S27): 2.6mm, 2.7mm

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.

A new aluminium servo horn designed specifically for IF18. 23T specification for servos made by Sanwa and KO. By making the shape of the arm offset it is possible to achieve the maximum steering angle with a linear steering operation. Use in combination with R0259 Aluminium servo saver (up side).

Regular weight lip spoiler for 1/8 racing car body made of 0.8mm thick material. Includes a scale that is useful for precisely setting the lip spoiler height.
Compared to the light weight (R0284C), the lip spoiler itself is more rigid, enabling it to transfer downforce to the car body more effectively even at high speeds.

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.

Low-Friction Type Ball (Compatible with IF18-3/IF15-2)
Introducing low-friction balls optimized for the lower rear shock of the IF18-3!
Special surface treatment significantly reduces friction, enabling smooth suspension operation.
The ball center height is set lower at 2.95mm (from 3.1mm) compared to the previous model (R0332), preventing interference with the wheel.

Furthermore, it's also ideal when converting the IF15-2 rear upper rod to 5.8mm!
The flange diameter at the base is reduced by 1mm to ensure clearance with the wheel. The inner side features a low-profile design that increases the slant angle, enhancing grip performance during acceleration.

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.

Increase steering angle

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.

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.
