Technical Summary

The M07-11 graphite upper bumper is a dedicated replacement component for the TAMIYA M07 chassis. Produced as a single-piece graphite unit, it focuses on reducing upper-mount mass while increasing torsional rigidity relative to stock polymer bumpers.

Mounting follows the standard upper bumper location on M07-series kits and utilises the chassis' original mount points and common hardware where applicable. The part is supplied for direct replacement without requiring bespoke brackets on unmodified chassis.

From a setup and tuning viewpoint, this graphite upper bumper shifts the stiffness distribution at the front bulkhead, affecting steering transient response and roll onset. Racers should expect a crisper initial steering input and may compensate with small spring or damper adjustments to recover desired balance. Use only within scale RC tuning contexts.

Will this change steering transient response?

Yes. Raising local stiffness at the upper mount typically sharpens steering transients; consider small damping increases to moderate snap steer.

Any recommended setup starting points?

Start with minimal changes: test with existing springs, then soften front springs or increase rebound damping in small steps if the front feels too nervous.

Is the part intended for competition use?

It is designed for performance-focused builders and racers seeking precise tuning options, but it remains a scale RC replacement component rather than an OEM chassis part.
