These double aluminum rollers provide a deliberate performance upgrade for Mini 4WD cars where predictable roll behaviour is key. The light blue finish identifies the 18-19mm variant and the components are compatible with common Tamiya mounting arrangements.
Engineered to balance rigidity and low inertial mass, the rollers reduce lateral displacement while preserving acceleration characteristics. The 18-19mm sizing is chosen to improve cornering precision on technical circuits and high speed sweepers alike.
Use these rollers to fine tune entry and exit stability; small spacer changes and alignment tweaks will noticeably affect lap consistency. Their low weight assists in maintaining momentum during quick direction changes while delivering dependable chassis feedback.
