The Tamiya 15425 JR FRP Rear Double Roller Stay adds stability to Mini 4WD builds by fitting lightweight FRP stays with 19mm low friction rollers. Built to help reduce drag through corners, this stay is aimed at racers who want more predictable handling without sacrificing speed.
This rear double roller stay fits Mini 4WD PRO, Super II, Super X, Super XX, and VS chassis. The 19mm low friction rollers cut cornering resistance to produce smoother lines through turns, while the FRP construction keeps weight low and strength high.
The set ships with the mounting hardware you need, including hex mounts and aluminum spacers, plus a small wrench for adjustments. Installation is straightforward and the parts are arranged so both newcomers and experienced tuners can mount and tweak the stay quickly.
