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.
Prevents the side belt from falling off when a heavy load is applied to it.
Pinion gear with improved durability compared to the standard part, achieved by reviewing the material and coating.
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.
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)
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.
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.
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 new aluminium center bulkhead ensures chassis rigidity in the center section of the car. Helps with traction and added stability in high grip situations.
This is an upgraded version of IF15front one-way set. By replacing the bevel gear with the newly-designed one-way plate, The one way dampening effect can be better controlled. In addition, this set enables the operation to be more stable for a longer period of time. Silicone oil of a part number between 100000 and 500000 and rubber glue or silicon sealing agent are required for assembly.
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.
