This graphite upper bumper plate is a direct replacement for the TAMIYA TT-01 upper bumper, specified as TT01-M18U. The graphite construction increases stiffness at the front mounting area while minimising added mass, improving the fidelity of steering inputs for competitive on-road tuning.
Mounting aligns with the original TT-01 upper bumper points so standard fasteners are usually retained. No extra drilling is required on standard TT-01 configurations; verify bumper to steering clearances during assembly to avoid interference at full lock.
From a setup perspective the graphite plate provides a predictable change to nose rigidity. Use it in conjunction with spring rate, damper and toe adjustments to fine tune turn-in characteristics and mid-corner balance for track-focused performance.
