Tamiya 84031 - 1/10 F103RM Tunable Formula Chassis Kit  [84031]

Introduction to the F103RM Formula Platform

The Tamiya 84031 - 1/10 RC F103RM is built for enthusiasts who prefer detailed setup and track-side tuning. Its design borrows from classic formula geometry while offering modern parts for improved handling.

Reduced Rotating Mass and Gear Case Adjustability

Featuring the 53248 Formula Lightweight Diff Joint Set, the F103RM reduces inertia for livelier acceleration. The 53257 Formula Height Adjustable Gear Case makes it straightforward to alter ride height to suit differing tyre setups and grip levels.

Refined Suspension for Stable Cornering

Ride smoothness is enhanced by the 53273 Formula Car Rear Suspension Ball Mount Set which replaces O-ring supports with ball mounts to reduce chatter and improve roll. The front uses a kingpin coil spring arrangement while the rear employs a T-bar with friction plate and coil spring for predictable balance.

What Comes in the Kit and What You Need

The kit includes full bearings and a standard ball differential for reliable drivetrain performance. Electronics such as servo, R/C system, ESC, motor, battery and charger are required separately. The supplied RM type body is unmarked so you can personalise the livery.

The Tamiya F103RM is a great base for tuners who enjoy tweaking geometry and drivetrain parts to suit different asphalt conditions and driving styles.
