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.
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.
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.
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.
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.
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.
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)
Facilitates adjustment to reduce vehicle width when using wide offset tires.
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.
Oversized wheel hubs to better fit tires with large wheel hex mounting. Prevents misalignment and increases wheel stability. (Matrix tires recommended).
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.
Pinion gear with improved durability compared to the standard part, achieved by reviewing the material and coating.
