R0312 - 7.8mm BALL(for 13.5 Knuckle Base)

For rear only

Spare part for R0337

As used by the team drivers at the 2019 World Championships. The chassis offers increased corner speed while also offering a smoother feel, this has been achieved by changing the shape of both the front and the rear of the chassis.
It is also possible to change the characteristics for different track conditions by adding a carbon plate (sold separately) to increase rigidity of the front section and adding an M3 screw to the rear. 

A new lineup of pinion gears for the IF18-2 with a hard coating on 7075 aluminium material. Offered in all teeth sizes to fine tune gear ratio according to the engine and track layout.

Body stiffener for 1/8 body (Only large type for rear)

Body stiffener for 1/8 body (Only small type)

A spacer/insert set that matches the fuel tank capacity of IF18-2 with the regulations of international races such as IFMAR. The thinnest spacer is 0.5cc, allowing you to make fine adjustments to the tank capacity by increasing or decreasing the number spacers.(1.5cc Upper&Bottom Spacer each 1pc.0.5cc Spacer 2pcs,M3x10mm/M3x12mm/M3x14mm screw each 1pc)

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.
