This new option part for IF18 is a set of 4 large diameter aluminium counter sink washers M4x12mm. Used for fixing the engine mounts to the chassis the flat surface means a super secure fitting and sufficient range of movement for all gear mesh. They can also be used with other 1/8 scale on road models.
To change ackerman angle (more increase angle of outside front tyre)
Bearing support rigidity has been greatly improved by increasing the roundness of the bearing cavity area as much as possible using a special molding process that has never been used before. This provides a higher consistency of rear traction.
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).
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.
Titanium UFO head screw. Offers a lightweight design while maintaining contact surface area.
Uses a softer material than the standard R0303-01. Increases crash resistance. The steering response is also mild.
(M2x8mm Flat Head Screw is not included.)
Regular weight lip spoiler for 1/8 racing car body made of 0.8mm thick material.
Compared to the light weight (R0284), the lip spoiler itself is more rigid, enabling it to transfer downforce to the car body more effectively even at high speeds.
