Track Upgrade: OTW111B 7075 Chassis for OPTIMA

The OTW111B hard main chassis brings a noticeable step up in structural stiffness for the Kyosho OPTIMA. Constructed from 7075 alloy, it is aimed at hobbyists who want a tougher main plate that handles sustained stress on the track.

Why 7075 Alloy Matters

7075 alloy is chosen for its high strength-to-weight ratio and resistance to bending, helping to keep the chassis shape under hard landings and heavy corner loads. That stability supports consistent setup tuning and predictable lap-to-lap behaviour.

Designed for OPTIMA Fitment

Engineered to align with OPTIMA mounting points, the OTW111B offers a bolt-in style replacement that maintains centre of gravity and balance while improving resilience during competitive running.
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.

Does the OTW111B suit every OPTIMA chassis variant?

The OTW111B is produced to fit the range of Kyosho OPTIMA models that share the standard main plate layout, enabling a reliable upgrade path.

Will this chassis change my car balance?

The 7075 plate is durable while offering a comparable mass to many aftermarket plates, so balance changes are minimal; drivers should recheck trim and ride height after fitting.

Is special maintenance required for 7075?

Routine inspection for fastener tightness and any impact damage is recommended; 7075 is tough but benefits from regular checks to keep performance consistent.

Can I run this on carpet and asphalt tracks?

Yes, the added rigidity helps on both carpet and asphalt by reducing chassis flex, but suspension settings may need tuning to match surface grip.
