Strength and Fit: OTW111B Chassis for OPTIMA

If you want to sharpen your Kyosho OPTIMA's on-track behaviour, the OTW111B hard main chassis is a direct upgrade. Machined from 7075-grade material, this chassis increases rigidity and resists deformation for more consistent lap times.

Benefits of 7075 Alloy

7075-grade alloy delivers high tensile strength and improved resistance to bending under load, which helps reduce chassis flex during aggressive cornering. That extra stiffness often translates to crisper steering feel and steadier handling at speed.

Compatibility with Kyosho OPTIMA

Made to match the Kyosho OPTIMA mounting points, the OTW111B installs with the original layout for a straightforward swap. It preserves the balance of the car while raising the overall durability for frequent track use.
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 the OTW111B fit all OPTIMA variants?

Yes, the OTW111B chassis is designed to fit the Kyosho OPTIMA family of models, allowing a direct replacement of the stock main plate.

What handling gains should I expect from 7075?

You can expect reduced flex and a firmer response through turns, which helps with precise steering input and improved stability at higher speeds.

Is the installation complex for club racers?

Installation is generally straightforward using the OPTIMA's existing hardware, though check chassis alignment and suspension geometry after fitting to ensure optimal setup.
