The MST RMX 4 S PRO 1/10 RWD Drift Car Kit is an adjustable rear-wheel-drive chassis developed for drivers who want a versatile platform for both recreational and competitive drifting. The RMX 4 generation introduces a modular chassis layout, multiple wheelbase options, refined steering geometry, and quick-access components that make setup changes and maintenance easier.
The RMX 4 S PRO can be configured with 257mm, 266mm, or 275mm wheelbases, allowing it to accommodate a broad selection of 1/10 drift bodies. Glass-fiber reinforced nylon components provide a balance of rigidity and low weight, while the quick-release battery system supports standard and low-profile shorty LiPo packs.
An anti-torque four-gear transmission provides the standard drivetrain configuration and can be converted to a three-gear layout for different power-delivery characteristics. The included gear differential, three-position motor mounting system, and adjustable ESC placement give drivers several ways to alter weight distribution and chassis response.
Short rear suspension arms are used to influence lateral weight transfer, while front and rear bullhorn-style shock towers provide a wide range of damper positioning options. The S PRO package includes TR56 aluminum oil dampers with progressive DK short springs, along with ATK V3 steering knuckles designed to provide a large steering range.
A removable rear subframe provides convenient access to the rear suspension, while the quick-release gearbox simplifies differential servicing. A floating servo mount helps separate servo operation from chassis flex, and the S PRO version includes a servo saver damper for additional steering system protection.
