R0392 - CHASSIS STIFFENER F (IF18-3/CARBON)

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

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.

IF18-3 setting parts

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.

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.

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.

This tension roller flange prevents the middle belt from accidentally falling off in high load situations such as high temps or extreme high traction. Fixed in place so as not to increase rotating mass of the roller it is also shaped to prevent any step between the belt and the flange. Offered in black and titian colour. (Can also be used for IF15. Please use the included M3x15mm screw.)

The use of lightweight titanium screws inside the two-speed unit contributes to improved engine pickup. The screw head is shaped to achieve the lightest weight possible.

A special manufacturing process ensures long life and consistent performance.
As the overall length is approximately 11mm,
please use it together with R0413 CLUTCH SPRING HOLDER (for R0412).

IF18-3 setting parts

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.
