Upgrading with Tamiya 94721 Double Aluminium Rollers

The Tamiya 94721 Double Aluminium Rollers are a focused upgrade for Mini 4WD modellers seeking steadier cornering on varied track layouts. The two-roller configuration uses a 9mm lower roller and an 8mm upper roller to balance stability and turn responsiveness. Aluminium bodies reduce friction against course walls, which helps maintain momentum through chicanes and bends. They are compatible with both Mini 4WD and Mini 4WD PRO cars, allowing straightforward fitment across popular chassis.

Each roller is approximately 0.6g in weight, so they add very little to the car while delivering performance benefits. The blue colouring is neat and suits both race and display builds.

What setup changes pair well with these rollers?

They work well alongside low-friction guides and lightweight wheels; small tweaks to ride height and weight balance will maximise the handling gain.

Do they need special bearings?

These rollers are designed for standard roller mounts and do not require bespoke bearings, though high-quality bearings can further reduce drag if desired.

Are the rollers suitable for display models?

Yes, the blue finish and neat aluminium look suit display cars as well as race machines, offering both form and function.
