R0388 - UPPER DECK STIFFENER (IF18-3/CARBON)

IF18-3 setting parts

Uses lightweight carbon material. Chassis rigidity can be increased while suppressing weight increase. Improves steering response.

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.

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.

Compared to the kit-standard O-rings, the slightly harder compound generates subtle friction with the shock shaft, enhancing support rigidity.
This helps suppress chassis roll and improves stability on high-grip or flat surfaces.

Weight has been reduced by F:0.3g R:0.5g, removing this unnecessary material has improved rotational balance. Reduced clearance in the thrust direction helps maintain wheel stability during running.

R0342 is made with carbon mixed material to greatly increase the rigidity of the parts. The rear upper arm and wheel shaft support are more rigid, and rear traction is improved at all speeds.

Machined from high quality A7075 aluminium material. IF18-2 knuckle upper and lower insert. Prevents misalignment during a crash and enhances steering response during cornering. This bushing is used for -1mm/+1mm (trail/reverse trail) of the upper pivot.

When assembling these parts first remove the front knuckle upper. Place the offset bush into the knuckle upper from the outside. Then pass both M3x14mm slim head screws through the knuckle upper from the inside and tighten the 3mm nylon nut on the outside.

IF18-3 setting parts. Harder material than R0352S included in the kit for better steering response

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.
