Yokomo BD9 Front Topdeck 2.0mm Aluminium - Arrowmax AM-920023 Performance Part  [AM-920023]

BD9 front topdeck replacement

The Arrowmax AM-920023 is an aluminium 2.0mm front topdeck made to suit the Yokomo BD9 FWD touring platform. Its metal construction provides a reliable way to change front-end stiffness while keeping original suspension geometry intact.

Fitment centres on the BD9 front chassis area, where the topdeck bridges the shock tower and bulkhead. Installation involves removing the existing topdeck screws and refitting the Arrowmax plate to the factory mounting points; no extra fittings are usually necessary.

On-track, a 2.0mm aluminium deck commonly gives a firmer front end and crisper steering input versus thinner plates, which can be beneficial for drivers chasing sharper turn-in. Introduce this part as part of measured setup changes and note how it affects front grip and mid-corner behaviour.
