This RC-scale graphite front chassis brace from Yokomo fits the B-Max4III and is intended to stiffen the front section to change handling balance and steering feel. The part modifies how the front end reacts to steering inputs and uneven surfaces for improved feedback.
Fitment details: the item is named for the B-Max4III platform and is intended to match that chassis mounting layout. No adapters are supplied; check hole positions on your current front bulkhead prior to fitting to prevent undue stress on mounting screws or the chassis.
Installation tips: use the OEM mounting hardware or screws of equivalent diameter, tighten progressively, and confirm preload to avoid overtightening sensitive composite areas. Make incremental on-track tests to assess how added front stiffness changes understeer and transient turn-in.
Care and checks: avoid heavy impacts with graphite parts and inspect for fine cracks after any crash. Clean gently with a soft brush and a mild solvent safe for composite materials, and verify fastener tightness after initial runs.
