This graphite upper bumper is made to suit the TAMIYA M04M 1/10 on-road chassis and is supplied as part number M04M-09/WO from 3Racing. The item replaces the factory upper bumper section to modify front stiffness and to provide an alternate mounting interface for bodywork or braces.
Fitment and effect: intended for the M04M layout, the component stiffens the front assembly and can sharpen steering response and chassis feedback during setup sessions. It is a lightweight hop-up designed for hobbyist tuning tasks.
Fitting notes: the bumper attaches at the stock upper bumper screw points on M04M-pattern parts; common hand tools and the original fasteners are normally enough. After installing, verify there is no contact with steering links or servo horns and add small shims or trim the body where required.
Care and use: graphite gives a stiffness advantage at low weight, so monitor mating surfaces for wear and keep fasteners checked after initial use. Combine this bumper with suspension or tyre changes to judge handling improvements.
