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

Front lower arm aluminium upgrade for WR-02C

This aluminium front lower arm is an aftermarket option made for the Tamiya WR-02C platform, sold under model WR2055. It replaces the factory plastic lower arm to provide increased toughness and a more rigid front suspension link.

Function on the car: the arm forms a key structural element of the front suspension and has direct influence on steering response and camber behaviour. Aluminium reduces unwanted flex compared with stock plastic components, which helps retain setup consistency during longer running sessions.

Fitment notes: intended for WR02C specification only and normally fits using the original mount points and hardware where compatible. Always check the linkage geometry and hub clearance after installation to ensure correct operation.

Tuning notes: swapping plastic for aluminium changes compliance and can sharpen steering input. Reassess shock settings and anti-roll tuning when introducing this component into your setup.

GPM model WR2055 offers a straightforward aluminium replacement for WR02C front lowers for hobbyists seeking improved durability; verify fit and hardware before final assembly.
