Check the compatible parts and machines for each chassis!
We will introduce in detail each type of mini 4WD chassis that can participate in the Mini 4WD official competition. You can check the information of the corresponding upgrade parts and which chassis is used for which kit. Please help find your new machine and consider your machine settings.
※ Number of published specifications may change by kind of roller or tire.
※ The upgraded parts displayed in “Supported parts” may be limited in usable parts depending on the combination with the chassis (Example: Only pinion gears can be used among gear sets). Please also check the item of “Supported chassis” listed on the explanation page of each upgraded part.
