Tamiya 94945 - JR Lightweight Double Aluminum Rollers (13-12mm) Precision Race Rollers  [94945]

Lightweight Tamiya 94945 rollers for sharper cornering

The Tamiya 94945 - JR Lightweight Double Aluminum Rollers (13-12mm) bring a targeted weight reduction to Mini 4WD builds, making them roughly 20% lighter than the older Item 15398. That lower mass helps reduce inertia through turns, producing more predictable handling and cleaner lap performance on typical circuit layouts.

These double aluminum rollers fit both standard Mini 4WD and Mini 4WD PRO setups and are suited to racers who tune alignment and roll angle for maximum speed. The twin-roller arrangement improves lateral balance when negotiating chicanes and banked corners without adding drag.

Built to withstand frequent track use, the rollers offer a durable upgrade path for hobbyists and club racers. They are a practical choice when you want to lower rotating weight while keeping reliable track contact and long service life.
