Better stability through turns with the Tamiya 15399 brake parts

The Tamiya 15399 JR MS Chassis Brake Parts Set provides a straightforward way to improve Mini 4WD stability on competition style tracks. Designed for MS chassis cars, the set adds adjustable braking elements to control speed during lane changes and slopes.

How the sponge brakes help on track

Sponge sheets are fitted to the lower chassis so they lightly contact the track at crucial moments, creating a consistent braking effect that reduces bounce and keeps you on the racing line. Two height options let you set engagement for different wheel sizes.

Adjustments and contents

The set contains two sponge types offering different levels of deceleration, and the sponge strips are divided into four parts for width tuning. Two hex shaft lengths, 45mm and 72mm, are supplied to broaden compatibility across Mini 4WD PRO machines.

Is the Tamiya 15399 suited to race day setups?

Yes, the brake set is useful for race setups where managing speed into corners and across slopes can improve lap consistency, especially on technical circuits.

What is the easiest way to test braking settings?

Start with a single sponge type at the lower height and run a few laps to note behaviour. Then try the alternate sponge and adjust width by removing or adding segments until the car holds its line through key sections.

Will the kit fit other Mini 4WD chassis?

The parts are made for MS chassis mounting. Other chassis may require modifications, but the supplied 45mm and 72mm hex shafts increase the chances of fitting a range of PRO machines without major changes.
