R0389 - MAIN SHAFT STIFFENER (IF18-3/CARBON)

Repair parts for R0394

Upper arm holder machined from 7075 aluminuim material. The strength and rigidity are increased providing higher corner speed in certain conditions. The black anodized finish complete with Infinity logo also add a cool look to your car.

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 central alignment of the upper pivot (0mm kit standard zero offset).

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.

This light weight lip spoiler set has a reduced weight of approx 5g including fastener and nut. Recommended for use with a lightweight bodyshell. Special carbon style features a printed INFINITY logo.

A brass battery plate that concentrates the weight in the center of the car body and increases the chassis rigidity achieves higher driving stability. In particular, it is easy to control on a high-grip road surface and prevents traction roll.

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

By greatly increasing rigidity in the rear section of the  chassis, the car's turning ability is noticeably reduced, making it easier to manoeuvre on extremely low-grip surfaces or high-grip surfaces where traction roll could be a problem.

The material and coating have been updated to significantly improve crash resistance and durability compared to the standard items. The shaft is highly durable and resistant to scratches even after long periods of use.

IF18-3 setting parts

The drivetrain of the IF18-3 has been lightened to improve response during acceleration and deceleration.
The weight is approximately 7g lighter than the 8mm shaft.

New stabilizer stopper for IF18-3 front stabilizer.
By making the contact surface with the bearing spherical, smoother movement of the stabilizer is acheived.
Durability has also been greatly improved by using steel.
Available in 2.3, 2.5, and 2.7mm.

Compatible stabilizers
Stopper 2.3mm (R0382S23): 2.0mm, 2.1mm, 2.2mm, 2.3mm
Stopper 2.5mm (R0382S25): 2.4mm, 2.5mm
Stopper 2.7mm (R0382S27): 2.6mm, 2.7mm

Making the material harder than the standard kit version the flex of the arm is reduced and rear traction is increased. Offering increased consistency in high grip and high temperature conditions.
