Aluminum rear underguard

This is an RC-scale aluminum rear underguard produced for the TAMIYA Hornet EVO 58742 chassis and offered by JAZRIDER as model JR-THNE03-LB. The component is presented in anodized blue and is intended to mount at the rear lower section of the buggy to protect the chassis and influence rear-end rigidity.

The description focuses on practical fit and tuning role: the underguard serves as a protective plate for the rear underside, resists abrasion from impacts and track contact, and provides a measurable change in lower rear stiffness that drivers can use when refining handling on carpet or hardpack surfaces. Because this is a scale RC part, fitment is described specifically for Hornet EVO 58742 and no other chassis is implied.

Installation notes: the underguard is designed to align with existing rear mounting points on the Hornet EVO 58742 chassis, keeping original screw patterns and clearances. Installation typically replaces the stock plastic plate with the anodized aluminum unit and may require checking clearance around the rear suspension and bumper areas to ensure no interference with normal travel.

Tuning considerations: swapping from plastic to an aluminum plate shifts the rear lower stiffness and contact behavior, which can make the car feel more stable on high-speed corner exits while possibly increasing sensitivity to bumps. Use this underguard as one element in a broader setup process that includes shock tuning and anti-roll adjustments to balance rear traction and steering response.
