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

For rear only

Prevents the side belt from falling off when a heavy load is applied to it.

Spare part for R0390.

Super low friction rubber belt

Lightweight and rigid flat head screw made of titanium, with the optimum length for installation of 2-speed spur gears for more secure tightening.

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.

Stainless steel material offers supple flex characteristics while adding extra weight for improved stability on high grip surfaces. This option part promotes mild steering characteristics.
