Race-Oriented Graphite Upper Bumper for Tamiya M04M

Engineered for competitive setups, the 3RACING graphite upper bumper increases front-end rigidity on the Tamiya M04M to stabilise steering inputs and maintain alignment through high speed sections. It is intended for drivers who tune their chassis for predictable lap-to-lap performance.

Material and Tuning Impact

The graphite construction of the 3RACING bumper reduces compliance compared to stock plastic, preserving suspension geometry under lateral loads. This consistent behaviour aids in tuning damping and roll characteristics, allowing finer adjustments to front end balance.

Installation and Setup Notes

The 3RACING bumper matches the factory mounting layout for the Tamiya M04M, enabling quick installation. When fitted, assess front toe and damping settings as the added stiffness can change transient response; small adjustments will help integrate the bumper into a tuned race setup.

How does the graphite bumper affect dynamic roll?

Reducing front compliance tends to lower undesired roll at the front, which can make the car respond more quickly to steering inputs. You may need to soften front damping slightly to retain mid-corner traction.

Is there any recommended hardware for mounting?

Use the OEM mounting points and hardware; inspect threads and replace worn screws. For competition use, consider using lock washers or medium-strength thread locker to prevent loosening.

Will the bumper change front-end weight distribution?

Graphite is light compared to metal parts, so weight shift is negligible. Handling changes stem primarily from altered stiffness rather than added mass.
