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

Rear aluminium reinforcement for DT-03

This aluminium rear bumper is a direct aftermarket replacement for the Tamiya DT-03 chassis, made as a scale-friendly reinforcement to replace the factory plastic rear bumper. It adds a firmer mounting point at the rear and provides basic impact protection during track sessions and club runs for 1/10 touring cars.

The design prioritises precise fit with DT-03 rear mounts and gives owners a rigid aluminium option instead of the stock plastic piece. The added stiffness helps preserve rear geometry under light impacts and supports consistent behaviour when adjusting rear-end tuning or setup.

Fitting is generally straightforward on DT-03 platforms: the bumper installs using the existing mounting points and keeps alignment with the chassis rear mounts. Choose this part when you need a durable metal replacement for regular circuit use or when small setup changes rely on a stable rear attachment point.

Select this aluminium rear bumper to preserve rear mounting geometry and add everyday protection for 1/10 DT-03 touring car setups, keeping tuning consistency and durability in mind.
