To match the increased power of my DT-04, I have been working hard on chassis stiffening.
This time, we reach the final milestone: the complete aluminum upgrade of the suspension.
Here is the build update for ultimate high-speed stability.

Assembly and Front-End Installation
I installed these components sequentially to beef up the front chassis section.

Replacing stock plastic parts with aluminum drastically increases structural rigidity.
This directly improves suspension articulation and steering response.

The mechanical look of the aluminum parts gives the front end an aggressive stance.
Full Aluminum Suspension Completed!
With this latest addition of parts, the complete aluminum conversion of both the front and rear suspension is finally finished.
Key areas including the **uprights, front hubs, rear hubs, upper arms, and lower arms** are now fully unified with high-precision aluminum components.
Slop and play have been reduced to an absolute minimum, ensuring sharp, precise handling even at extreme speeds.
Conclusion
Using Eagle Racing aluminum parts successfully solves the stiffness issues for high-speed DT-04 builds.
The full aluminum suspension upgrade contributes heavily to stability during high-speed runs.
This is the ultimate recommended upgrade for anyone pushing their DT-04 to the absolute limit.
