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.

New rear shock tower features a body mounting position 3.5mm lower than std, contributing to a lower center of gravity.
By using T266 Alu HBP mount (black/2pcs) it is also possible to utilize horizontal style body mounting style.
The shock mounting positions have been reduced to 3 offering increased strength and crash resistance.

For IF15 / IF15W
Developed based on team driver feedback
A new carbon camber plate that can be adjusted in fine steps. The diagonal direction of the holes incorporates the latest setups for the IF15.
The bottom hole is the same original hole 2 (lower), the more you raise it, the more calm the rear will be.
(Part of the outer ball end needs to be cut)

For IF15 / IF15W
Developed based on team driver feedback
Carbon camber plate (G159) that can be adjusted in a diagonal direction that incorporates the latest setups for the IF15.
In addition, the A-arm type camber link enhances rigidity and is a set of parts that greatly support rear grip.
The bottom hole is the same as original hole 2 (lower), the more you raise it, the more calm the rear will be.

This shock tower is used in combination with a specially developed short-type shock.
The suspension stroke is equal to that of the standard type, and combined with the low center of gravity, the shocks provide increased response and cornering.
The front and rear mounting positions are also carefully designed to keep the upper and lower mounting surfaces the same.
The upper fixing surface is offset by 1mm to keep the upper and lower mounting surfaces the same, the shape takes advantage of the machined A7075 material.

In the case of use with IF15W the racing body SMJ C235 can be optimized and mounted 3.5mm lower when using G147 short front shock set.

Features the same design shape as G154 rear shock tower (standard / carbon)
but designed to be used in combination with a specially developed short type shock.
The total shock length is 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.
The body mount is 3.5 mm lower (one step of the body pin), which also contributes to lowering the center of gravity.

The shock mounting positions have been optimised to only the three inner positions, allowing for extra strength in this area in the event of a crash.
