Tamiya DT-03 Aluminium Rear Bumper by GPM DT3003R  [DT3003R]

Aluminium rear bumper for DT-03

This aluminium rear bumper is a direct aftermarket replacement designed for the Tamiya DT-03 chassis, intended as an RC-scale reinforcement part that replaces the stock rear bumper element. The part’s role is to add a stiffer mounting point at the rear and offer basic impact protection for the rear section during track sessions and club runs.

The design focuses on compatibility with DT-03 rear mounts and on providing a rigid aluminium option for owners who want a metal alternative to the factory plastic piece. That rigidity helps keep rear geometry consistent under light impacts and during tuning adjustments related to rear-end behavior.

Installation is typically straightforward for DT-03 platforms: the bumper replaces the original bumper and installs with the same mounting points, maintaining alignment with the chassis rear mounts. Use this part when you need a durable option for regular track use and when making small setup changes that depend on a consistent rear attachment point.

Choose this aluminium rear bumper when you want a metal replacement to preserve rear mounting geometry and add basic protection for 1/10 DT-03 touring setups, keeping tuning consistency and durability in mind.
