Infinity IF18-II

NEWLY DESIGNED FRONT SECTION

By splitting the front knuckle into upper and lower parts, three types of trails can be set + 1mm / 0mm / -1mm The position of the upper arm pivot has changed significantly from the previous model, offering more choice in steering characteristics. In addition, the section around the lower pivot has a split structure (by increasing or decreasing the lower spacer) that allows the roll center to be adjusted. The structure that looks like an inverted front knuckle expands the adjustment range of the geometry. It has a structure that allows you to easily change the camber angle on the spot even just before the race.

UPPER AND LOWER ARMS

The upper and lower arms have a newly designed shape that is resistant to crashes. In addition, the rigidity can be adjusted by attaching a carbon plate (optional setting part) to the lower arm. The turnbuckle rod used for the lower arm is also made of high-strength steel. The lower arm pivot 7.8mm ball is hard anodized for smooth movement while maintaining excellent surface condition for long periods of time.

UPPER AND LOWER ARM HOLDERS

The upper and lower arm holders are also newly designed. Designed to be both lightweight in finish and still ensuring sufficient strength. 6 types of mounting positions can be selected for the upper arm holder by exchanging bushes (3 types). The lower arm holder also offers an IN and OUT pin position by replacing the bushing.

WIDE TYPE FRONT ANTI-ROLL BAR

Adopts a newly designed wide type front anti-roll bar. By lengthening the reach, the effect of the anti-roll bar is softened at the initial stage of suspension movement. While showing mild steering characteristics, the anti-roll bar becomes more effective later in the the corner. The 5.8mm anti-roll bar ball uses hard steel with a smaller boss. (Kit is front / 2.4mm, rear / 3.0mm. 2.7mm is also available as an option)

VARIOUS OPTION PARTS AVAILABLE

Various option parts are available. Hard materials are available as an option for the front knuckle, upper & lower arm, and upper & lower arm holder. You can tune your car according to the track conditions and driver's taste.

OPTION CARBON WHEEL PLATE

A carbon wheel plate which attaches to the front knuckle is also available for the IF18-2. With this plate its possible to achieve sharper steering in high speed corners.

OPTION FRONT ANTI ROLL BAR

To ensure you are covered for all driving conditions, the front anti-roll bar is available in steps of 0.1mm from 2.0mm to 3.0mm. (Kit standard is 2.4mm)

OPTION ALUMINIUM KNUCKLE

By switching to the optional aluminum knuckle base 13.5, the front roll center of the IF18-2 is set to the lowest setting, and offers the sharpest turn-in while reducing the chance of traction roll at the initial stage of cornering on a high grip track surface. (A dedicated 7.8 mm ball is prepared separately. It is recommended to use a 2.7-3.0 mm stabilizer together)

FRONT BODY MOUNT

A long type front body mount post used by all team drivers is standard equipment.

FLUORINE COATED SHOCK CASE

Fluorine coated shock case is standard equipment.

FUEL TANK

The position of the O-ring on the tank lid cap has been revised so that it provides a perfect seal, and to minimise the expansion of the O-ring due to the difference in fuel composition to ensure stable pressure. The inner diameter of the nipple has also been optimized, contributing to the stabilization of fuel adjustment. Volume has been added around the fuel filter allowing for a stable fuel supply even when the tank is almost empty. Extra space has been created to allow the carburetor stroke to now be "straight" in a front to rear direction, making throttle linkage setup easier. In order to contribute to the fuel efficiency of engines that are becoming more powerful these days, the fuel tank capacity has been drastically set to "125cc over" as standard. By adding the color of OPT inside, it corresponds to the international regulation.

LOW FRICTION BELTS

Low friction type soft belts (R8001S, R8002S, R8003S) are used for all belts.

EASY MAINTENANCE

For ease of maintainence, the rear body mount shaft is now supplied with a stopper as standard. R0258

STYLISH FRONT BUMPER

Front bumper with Infinity logo marking

MARKED SPRING ADJUSTERS

Markings have now been added to the spring adjusters of the front and rear oil dampers. (New) To help with keeping the left and right adjustments uniform when adjusting the ride height, we adopted the INFINITY team driver's usual handmade marking. This is a small but improtant message from the INFINITY development department that we want INFINITY users to know that these small details will lead to correct car setup and more fun on track
