Front one-way differential for M18 allows you to fine-tune the management traits using this type of at this time great-handling micro racecar. Enables faster steering but decreases stopping performance, since simply the rear tires will brake. The one-way differential features top-notch one-way bearings, CNC machined diff body (blue), and high-strength lightweight CNC-machined outdrives made from HUDY Spring metal (available independently)
For use just within the front connected with M18, maybe not the trunk.
