Tamiya 15429 - JR High Speed EX Gear Set - MS Chassis/Gear Ratio 3.7:1 田宮迷你四驅車迷你四驅車後備配件齒輪 雙星孖星  [15429]

You can find at this time two gear ratios readily available for Mini 4WD racers to use on their MS framework devices, 4:1 and 3.5:1. This means that for a certain circuit often the previous might too slow even though the latter may be too fast. To solve this case and give racers another choice, this new set offers a 3.7:1 ratio gear set.
