Front one-way differential for M18 enables you to fine-tune the management characteristics using this type of currently great-handling micro racecar. Enables faster steering but decreases stopping performance, since essentially the rear tires will brake. The one-way differential features top-notch one-way bearings, CNC machined diff human body (blue), and high-strength lightweight CNC-machined outdrives produced from HUDY Spring metal™ (available separately)
For use simply inside the front side connected with M18, perhaps not the trunk.
