Tamiya 94966 JR Lightweight Double Aluminum Rollers Race Upgrade  [94966]

Track-focused upgrade using Tamiya 94966 lightweight rollers

The Tamiya 94966 Lightweight Double Aluminum Rollers are a targeted upgrade for Mini 4WD racers who want better stability through bends. These aluminium rollers are lighter than earlier Tamiya sets, which helps reduce drag when they touch the track walls while keeping the car under control during high speed sections.

The kit uses a dual roller layout with a 9mm roller mounted lower and an 8mm roller above, a combination that balances agility and steadiness through corners. Designed to fit both standard Mini 4WD and Mini 4WD PRO machines, the rollers suit racers looking for a straightforward way to improve lap consistency without major chassis changes.
