G071-17 - 1st PINION GEAR 17T

By changing the position of the 2.0mm pin, stable rear grip can be obtained from low grip surfaces to high grip conditions.

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.

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.

Made of lightweight 7075 aluminum with hard coating.
Low gear ratio for short technical tracks.

R0262, R0263 Repair parts for accessories. 1mm short type "G084 BALL NUT 4.9 mm", they can be used for height adjustment of each pivot part of IF15.

These innovative clutch weights sit between the flywheel pins and offer a higher clutch meet than a normal type weights making them suitable for use with basic engines such as 12TG from OS. Set screws are included to adjust the weight and clutch meet pressure. Also usable for high power engines.

These engine mounts are specially designed for the O.S.12 engine. They are lowered and allow the engine crankcase to sit right at the chassis level contributing to a lower center of gravity.
The cooling fins on the sides allows the engine to better dissipate heat and help prevent overheating during a race.
(Do not use with non- O.S. engines as the crankcase and chassis may interfere with each other.)

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.

Spare parts for repairing short shocks that can be used for IF15/IF15W.

Overall length of 24mm.

Spare part for G166.
