The black JAZRIDER JR-DT307-BK aluminium rear hub carrier is a solid option for those wanting firmer rear geometry on a Tamiya DT-03. It replaces standard plastic components to reduce movement and maintain alignment during spirited driving.
Using aluminium increases rigidity where it matters, helping the rear suspension behave more predictably. That stability aids steering accuracy and can make setup tuning more repeatable lap to lap.
Manufactured to match DT-03 mounting points, the carrier usually fits direct to the chassis. This keeps the upgrade quick and straightforward for workshop or trackside swaps.
