Tamiya 15399 JR MS Chassis Brake Kit for Mini 4WD - Track Tuning Pack  [15399]

Fine tune Mini 4WD handling with the Tamiya 15399 brake parts

The Tamiya 15399 JR MS Chassis Brake Parts Set is a practical upgrade for Mini 4WD fans wanting better control during complex track sections. Made for the MS chassis, the kit adds adjustable brake elements that help stabilise the car through lane changes and down slopes so you can keep speed where it counts.

Sponge brake action for tighter control

The included sponge sheets mount to the lower chassis and make light contact with the track at critical moments like lane transitions and slope exits. That contact produces controlled deceleration to prevent bounce or drift. Two mounting heights let you set the brakes for machines running small or large diameter wheels.

Configurable parts and fitment

The pack supplies two styles of sponge sheets that each give a different braking feel, and the sponge sections are split into four pieces so you can change brake width quickly. Two hex shaft lengths, 45mm and 72mm, are supplied to suit a range of Mini 4WD PRO machines.
