Tamiya 15399 JR MS Chassis Brake Parts Set - Precision Mini 4WD Brakes  [15399]

Control your Mini 4WD lines with the Tamiya 15399 brake set

The Tamiya 15399 JR MS Chassis Brake Parts Set helps racers manage speed and trajectory on tricky layouts. Built for the MS chassis, the kit gives you small, adjustable brakes that improve handling where accurate line keeping matters most.

How sponge sheets improve race lines

Sponge sheets attach low on the chassis so they touch the track at lane changes and slope sections, offering a predictable slow down that reduces ricochet and keeps the car in its groove. Two height settings let you choose the right engagement for different tyre sizes.

Options for setup and compatibility

You get two distinct sponge types to match circuit grip and handling style, plus the sponge is split into four strips so you can thin or widen the braking surface. The set also includes 45mm and 72mm hex shafts to suit a variety of Mini 4WD PRO builds.
