Tamiya 94721 Double Aluminum Rollers for Track Tuning

The Tamiya 94721 Double Aluminum Rollers make a practical upgrade for Mini 4WD racers who want more predictable handling on technical courses. The twin-roller arrangement pairs a 9mm lower roller with an 8mm upper roller to strike a good balance between straight-line stability and agile cornering. The aluminum construction reduces rubbing against course walls for smoother, faster laps. These rollers are compatible with both Mini 4WD and Mini 4WD PRO chassis, giving racers room to refine their setups.

Weighing just 0.6g each, these rollers add minimal mass while improving performance. The blue finish gives a neat visual accent that suits display or race builds.

How does the 9mm lower and 8mm upper roller affect balance?

The larger 9mm lower roller helps keep the car tracking straight while the 8mm upper roller allows quicker responses in corners, producing a stable but responsive setup.

Will these fit older Mini 4WD chassis?

Yes, they work with standard Tamiya Mini 4WD and Mini 4WD PRO models, though you should check your roller mounts to confirm clearance and fitment.

Any setup tips for better cornering?

Try mounting the rollers slightly lower and pairing them with low-friction side parts. Small tweaks to weight distribution and camber can further improve cornering on twisty layouts.
