Tamiya WR-02C Aluminium Front Lower Arm by GPM WR2055  [WR2055]

Aluminium front lower arm for WR-02C

This aluminium front lower arm is an aftermarket replacement designed for the Tamiya WR-02C platform and supplied by GPM as model WR2055. It replaces the stock plastic lower arm to provide a stiffer, more durable component for the front suspension assembly on WR-02C chassis variants.

Intended role: the part serves as a structural link in the front suspension that affects steering response and camber behaviour. Using an aluminium lower arm can reduce flex compared with the original plastic piece, which helps maintain setup under higher loads and during repeated runs.

Fitment and installation notes: this item is made for WR02C use only and should be fitted in place of the original front lower arm using the existing mounting hardware where possible. Check clearance and linkage geometry after installation, and confirm compatibility with your wheel hubs and steering blocks before finalising.

Tuning considerations: swapping to aluminium changes the suspension stiffness and can alter handling; expect slightly sharper steering feedback and a need to re-evaluate damping and roll characteristics. Use this part as part of an overall setup process rather than as a standalone change.

The GPM WR2055 aluminium front lower arm is a direct-fit aftermarket option for builders seeking a more durable front link for WR02C chassis setups; verify hardware and geometry during installation.
