The JR-WR201-GU front upright set is an aluminum replacement compatible with TAMIYA WR-02, DT-03T and Blitzer Beetle models shown in the product title. These machined parts feature a gun metal finish and are intended to replace the stock plastic uprights to provide a firmer mount for front hubs and steering links.
Installation aligns with the original WR-02/DT-03T mounting points and commonly reuses stock screws and pins. After refit, check steering geometry and wheel alignment since the stiffer uprights can shift toe and camber behavior under load.
Use the uprights as part of careful tuning: verify compatibility with your knuckles, wheel hexes and bearings and bench-test before running. The JR-WR201-GU focuses on scale suspension tuning and improved durability rather than drivetrain changes.
