Compact handling kit Tamiya 15403 JR Double Aluminum Rollers 9-8mm for Mini 4WD  [15403]

Tamiya 15403 JR Double Aluminum Rollers 9-8mm - dual-size handling parts

The Tamiya 15403 JR Double Aluminum Rollers (9-8mm) offer a compact dual-roller arrangement to sharpen handling on technical layouts. The lower 9mm element and the higher 8mm unit combine to control roll and lateral grip.

Role and Chassis Compatibility

These aluminium rollers are intended to cut down friction when the car contacts track barriers, permitting cleaner transitions along walls. They are suitable for standard Mini 4WD and Mini 4WD PRO machines, so they work with most factory and tuned frames.

Race Day Effects and Handling Notes

The staggered geometry helps the car retain pace through tight sequences by reducing sudden losses of traction at the rail. This makes them useful when you want steadier corner exits and improved line holding.
