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.
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.
G121-14 Chassis weight is 14g, half that of G0121 original optional chassis weight. Perfect for making finer setting adjustments. Can be used in all sliding weight positions and front bumper on IF15.
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.
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.
The use of 7075-T6 material and its slim profile make it both lightweight and highly rigid. Securely fastens the main chassis to the upper deck for more stable running on all surfaces.
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.
"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."
Prevents the side belt from falling off when a heavy load is applied to it.
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.
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.
