Fixing Front Drag on the MST RMX 4 (It’s More Than Just Aluminum Hubs)

If your RMX 4 wheels don’t spin freely, this setup change transforms how the car drifts. In this video, I break down a common issue with the MST RMX 4: front hub drag. While aluminum hubs are part of the solution, simply bolting them on isn’t enough. I install the ATK V3 aluminum front hubs and walk through the additional setup details that actually make the difference, including calipers and hexes, bearings, and other small tweaks that dramatically improve free spin and on-track performance. If your RMX 4 feels slow, inconsistent, or harder to drift smoothly, this video will help you understand why — and how to fix it correctly.
