Tamiya 15403 JR Double Aluminum Rollers 9-8mm - staggered aluminium rollers

The Tamiya 15403 JR Double Aluminum Rollers (9-8mm) are a focused parts upgrade for racers chasing smoother handling. The setup places the 9mm roller lower with the 8mm above to tune lateral contact with the track edge.

Why These Rollers Work and What They Fit

Aluminium construction reduces drag when the rollers brush the track wall, helping the car slide along without sudden speed loss. They are designed to fit both standard Mini 4WD and Mini 4WD PRO chassis layouts for easy adoption.

Practical Race Gains

Using staggered rollers spreads impact across two points and reduces abrupt grabs on corners, helping maintain momentum on twisty circuits and delivering steadier exits from sharp turns.

Are these rollers heavy compared to plastic ones?

Aluminium rollers are slightly heavier than plastic, but the durability and reduced friction often improve lap consistency, particularly on high speed sections.

Should I change gear or motor when fitting these?

Not necessarily. Start with your current setup and run test laps; you may find minor gearing tweaks improve acceleration without further hardware changes.

Can these rollers be used front and rear?

Yes. Depending on your setup you can mount them front, rear or both to tailor handling balance and how the car reacts to side impacts.
