Precision graphite upper bumper for TT-01 chassis

High-precision graphite upper bumper made for the Tamiya TT-01 chassis and identified as model GTT220. Fabricated to 2.5mm thickness, the part is intended to increase local rigidity at the front mounting point compared with standard plastic, improving structural support for on-road tuning.

The component is suitable for drivers seeking predictable front-end feedback or replacing a damaged factory upper bumper. The graphite offers a favourable stiffness-to-weight ratio so handling adjustments come from increased rigidity rather than added weight.

Installation follows the original TT-01 upper bumper mounting layout and replaces the OEM part in the same position, utilising existing chassis fixing points. Confirm variant compatibility and hardware fitment prior to installation to ensure accurate alignment.

What material properties should I expect?

Graphite provides high local stiffness with low density; it resists bending at the mount but can be more brittle under sharp impacts compared with plastic.

Are there recommended installation practices?

Use the original TT-01 mounting points and hardware where possible, verify hole alignment, and torque fasteners evenly to avoid stress concentrations around the graphite plate.

Will this require setup changes?

Expect measurable changes in front-end response; incorporate this part into a controlled setup process and adjust suspension and steering geometry as needed for optimal balance.
