Stiffer Main Plate Upgrade for OPTIMA

The OTW111B hard main chassis boosts the core stiffness of the Kyosho OPTIMA platform. Manufactured from 7075-grade material, it is aimed at improving chassis integrity during demanding driving.

Why Use 7075 on the Main Plate

7075-grade metal is valued for its high strength and reduced tendency to deform, which helps maintain suspension geometry under load and supports sharper cornering response.

Built to Match OPTIMA Mounting

Designed with the OPTIMA mounting layout in mind, the OTW111B offers a clean replacement that keeps the original mounting points and helps preserve the car's handling characteristics.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this replace my stock main chassis directly?

Yes, the OTW111B is made to be a direct main chassis replacement for Kyosho OPTIMA models that share the standard mounting pattern.

Can I expect better lap consistency after fitting?

Greater chassis rigidity typically leads to more consistent handling and repeatable setup, which can help with lap time consistency when suspension and tyres are dialled in.

Do I need to change screws or mounts?

Often you can reuse the OPTIMA's original screws, but verify thread fit and torque settings; replace any worn hardware as needed to ensure a secure installation.

Is the 7075 plate suitable for both practice and racing?

Yes, its durability and stiffness make it appropriate for both practice sessions and competitive events, though you may want to check setup after switching surfaces.

Any tips for keeping the chassis in top condition?

Regularly inspect for impact marks, keep fasteners tight, and clean mounting areas; these simple checks help maintain the performance benefits of a 7075 plate.
