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

DT-03 aluminium rear bumper upgrade

This aluminium rear bumper is a direct aftermarket swap for the Tamiya DT-03 chassis, created as an RC-scale reinforcement to stand in for the standard plastic bumper. It provides a stiffer rear mounting point and offers basic protection for the rear section during track days and club running.

Built for compatibility with DT-03 rear mounts, the part gives owners an aluminium alternative that keeps rear geometry more consistent under light impacts and during setup changes that influence rear behaviour.

Fitting the bumper is typically straightforward on DT-03 models: it replaces the original bumper using the same mounting points and preserves alignment with the chassis rear mounts. Fit this when you want a tougher metal replacement for routine circuit use or when precise rear attachment is required for repeatable setups.

Choose this aluminium rear bumper to protect the rear end and maintain reliable mounting geometry on 1/10 DT-03 touring car setups for everyday track use.
