Improved rigidity by using carbon-mixed nylon material. Stabilizes the rear grip and allows for increased racing line stability. It is particularly effective when used under high temperature conditions. *For identification, the ""H"" mark is printed by laser engraving.
Please apply grease to the screw tightening areas when assembling in cold temperature environments.
Mounted in the opening at the rear of the main chassis, it increases chassis rigidity at the rear end of the chassis and increases weight by approximately 13g to ensure stable rear grip. It is also effective when the track surface is high grip and traction roll occurs.
Use with G230 Carbon Rear Stiffener Set to expand the range of setting.
This is a spare part for the G0125 B adjustable front one-way set. This set helps control the one-way well even with soft silicone oil. We also recommend replacing the conventional one with this spare part.
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.
Pinion gear with improved durability compared to the standard part, achieved by reviewing the material and coating.
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.
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.
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.
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.
Pinion gear with improved durability compared to the standard part, achieved by reviewing the material and coating.
Oversized wheel hubs to better fit tires with large wheel hex mounting. Prevents misalignment and increases wheel stability. (Matrix tires recommended).
