This carbon upper plate reinforces the rear lower suspension arm on GT/Xb8 scale cars, intended for RC use only. When paired with a lower carbon stiffener it increases lateral and torsional rigidity of the lower arm assembly, reducing unwanted flex under high load.
The tightened lower arm assembly reduces unpredictable movement and helps maintain rear grip during cornering, offering a more controlled mid-corner balance. It is targeted at setups that operate on medium to high-traction surfaces where increased stiffness yields measurable handling gains.
Fitting is performed using the lower arm's existing attachment points; disassemble the rear suspension as required and confirm that fasteners sit correctly before final torqueing. Retune suspension parameters after installation for optimal results.
For competitors seeking to refine rear-end response on grippier tracks, this plate provides a compact upgrade to increase lower arm stiffness without altering core chassis geometry.
