This is a 9.5g chassis weight for IF15. By combining it with 14g and 28 chassis weights, the option parts already available, you can make finer tune-up.

20g chassis weights are now available to adjust the front/rear balance of the IF15 and IF15W. The 20g weight can be used together with the 9.5g, 14g, and 28g weights already available on the market for more detailed tuning of your setup.

Firmly fixing both ends of the upper suspension shaft with an E-ring and a stopper gives you added security from vibrations during long finals.

By replacing the original kit plastic part with this high-precision 7075 machined part, all flex and deflection will be eliminated, resulting in excellent consistency and sharp steering characteristics.

This new aluminium center bulkhead ensures chassis rigidity in the center section of the car. Helps with traction and added stability in high grip situations.

A high-quality 64 titanium ball screw set, when replacing the kit's standard φ8mm ball screws (front/steel, rear/aluminum), they reduce overall weight by approximately 3.3g and provides a light driving feel.

These 64 titanium ball screws are approximately 1.5 g lighter per piece than the kit's standard parts for the front (made of steel). This material change slightly reduces rigidity for a smoother feel.

These titanium ball screws contribute to improved grip by adding approximately 0.6 g of weight per ball screw compared to the kit's standard rear ballscrews (made of aluminum). In addition, the use of 64 titanium material with its increased rigidity improves response, especially on low to medium grip surfaces.

IF15/IF15Wに使用可能なショートショック専用のセッティングパーツ。
標準で付属の
2個穴-1.1mmピストンに対して
1個穴-1.3mmピストンはIF18-2のフロント用ピストンと同一サイズ、他に
3個穴-0.9mmピストンのタイプ(G124と同一サイズ)も発売。

ピストンの固定方法をIF14-2同様に極小のビスを採用し、ストロークを確保。

This is an option part for short shock for IF15/IF15W. 3 hole - 0.9mm piston. (3 hole - 0.9mm and 2 hole - 1.1mm piston is also available.

This piston is secured with an ultra small screw as used in the IF14-2 to increase stroke.

A dedicated 0.05" inch size tool is required. (A0100) INFINITY 0.05" hex wrench driver.

Used in combination with a specially developed short type shock.
The total shock length can be shortened by 4 mm.
The suspension stroke is maintained the same as the std shock type, and combined with the lower center of gravity, this offers sharper cornering and increased reaction.
