Tamiya 15357 PRO FRP Side Roller Extension Kit for Mini 4WD - Stability Upgrade  [15357]

Tamiya 15357 overview - Side extension roller mount for Mini 4WD PRO

The Tamiya 15357 Mini 4WD PRO FRP Side Extension Roller Mount increases the track width of compatible Mini 4WD PRO MS chassis to roughly 104mm. That added width helps steady the car through corners and reduces speed loss when negotiating technical layouts, making it useful for racers refining lap times.

Compatible chassis and simple fitting

This FRP side extension roller mount fits multiple platform types, including:

• Direct Use: Mini 4WD PRO MS chassis, Mini 4WD VS, Super X, Super TZ-X
• With Item 15242 FRP Front Plate: Super-TZ, Super-1

Fitting is generally straightforward on the supported chassis. Where needed, pair with the Item 15242 FRP Front Plate for Super-TZ and Super-1 models to ensure a correct installation. The part offers flexible setup options so racers can tailor ride width and roller positions to suit specific track demands.

Handling benefits and tune options

Widening the chassis with this mount improves lateral stability and helps maintain drive through corners. The FRP mount supports a variety of roller types and aftermarket damping or tyre choices, allowing fine tuning of corner entry, mid-corner balance, and exit traction.
