The Tamiya 15506 Lightweight Plastic Spacer Set lets hobby racers tailor small setup changes on Mini 4WD cars. Made from lighter plastic than metal spacers, they reduce component weight while remaining useful for routine track adjustments.
The kit supplies 20 spacers in five thicknesses: 1.5mm, 3mm, 6mm, 6.7mm and 12mm, covering common needs for roller spacing and axle positioning. Their material helps lower friction where the spacer may contact trackside features.
Tiny spacer changes can influence lap consistency and corner response. Use the Tamiya 15506 pieces to experiment with roller height and chassis alignment until you find the balance that suits your track and setup style.
