R0313 - 7.8mm BALL(for Familiar Upper arm)

1.5mm shorter

Reverse movement from the standard type

For rear only

This part is machined from high quality 7075 aluminium material. With the significantly increased rigidity the steering response will be improved. Plastic bushings to hold the suspension shaft and mounting screws are included.

Uses harder material than standard IF18 kit. Increases the rigidity of the suspension and improves the corner speed.

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.

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

Option part for IF18. This aluminum body mount spacer is to be used together with the optional 1 piece carbon mounting plate (R0198) Offers extra body post stability and is available in both silver and red.

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.

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)

This set of Φ8.5mm titanium ball screws is for use with the IF18-2. (Set includes 4 normal size and 2 long size) For smooth and light driving.

Compared to the standard plastic rear body mount, this new carbon mount increases the height of the body by 3mm (Almost the limit within the regulation of IFMAR). In addition, the cross-sectional shape of the carbon plate and A7075 adapter matches the latest body shapes such as XTREAM's Diablo and Protoform's R19 without any gaps. This allows the downforce to be transferred to the tires without loss and improving rear grip. The left and right carbon plates can be fine-tuned with set screws to accommodate individual body shapes. The connection to the car body can be made in three step width directions, and also absorbs the twisting of the mounting part when toe-in is applied.
