The Tamiya 15506 Lightweight Plastic Spacer Set provides a practical way to refine Mini 4WD setups. Produced from light plastic, the spacers reduce component weight compared with metal options while remaining suitable for routine tuning tasks.
Included are twenty spacers across five thicknesses: 1.5mm, 3mm, 6mm, 6.7mm and 12mm, giving a wide selection for fine adjustments to roller height and chassis clearance. The low friction surface helps keep performance steady when minor contact with rails or walls occurs.
Incremental changes using these spacers can improve stability and lap repeatability by allowing precise corrections to geometry and offsets. Use the set to experiment with small tweaks until your setup matches the track demands.
