Special rubber with excellent durability is used to achieve longer life than the soft rubber type of the kit's standard parts. Especially effective for IF15W with high grip wide tires.
Lowered shock tower for mounting short shock to IF15-2. As with the standard type, the damper mounting angle can be selected from 4 locations. Due to the lowered tower, the damper is 4mm shorter, offering a lower center of gravity. It is possible to enhance steering response and tune setup to your prefered driving feel. (Please use together with G147 short shock set)
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.
Steering knuckle plate for IF15-2 and IF15-2W, which allows for a greater steering angle of the outer tire in corners than the standard kit version.
This will make tighter cornering possible, and can improve high speed steering on larger tracks.
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.
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.
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.
Improved rigidity by using carbon-mixed nylon material. Improves steering response and enables increased racing line stability. It is particularly effective when used under high temperature conditions. *For identification, ""H"" mark is printed by laser engraving.
In order to efficiently draw out the power of the OS MAX 12TG, which is popular in Japan for its easy power, it has a lightweight flywheel and optimized weight for efficient power delivery. The specifications of each part, such as the yellow shoe, which has been processed to a thin 4mm thickness, have been determined in advance.
Optimized shape to accommodate the updated thickness of (G187) front knuckle plate (hard) adopted on IF15-2. Additionally, reducing the clearance of the opening compared to the original product to efficiently control the airflow, which is the original purpose of the knuckle plate.
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.
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.
Special rubber with excellent durability is used to achieve longer life than the soft rubber type of the kit's standard parts. Especially effective for IF15W with high grip wide tires.
