Rear Upgrades & Setup | MST RMX 4S Pro | RC Drift Build

In this video I upgrade the rear end and dial in the setup on my MST RMX 4S Pro RC drift car. After installing the front upgrades in the previous episode, it's time to improve the rear suspension and complete the baseline alignment before taking it for a drift. This upgrade focuses on improving rear suspension adjustability and drivetrain performance using aluminium upgrades, adjustable suspension components, and an LSD setup. After installing the rear upgrades, I use a setup station to dial in the alignment including camber, toe and ride height to establish a solid baseline. ⸻ Parts used in this upgrade: MST TMB Rear Hub Set 210740 MST LSD Set 210743 MST Adjustable Lower Arm Set 210731 MST Aluminium Spur Gear Holder 210742 MST Aluminium Rear Damper Stay 210729 MST POM Idler Gears 210734 MST Aluminium Suspension Mount Brace 210730 MST Adjustable Turnbuckle Set 210739 ⸻ This video is part of my MST RMX 4S Pro RC drift build series, where I’m gradually upgrading and tuning the car before finally getting it sideways.
