SHIBATA’s GRK最強決定戦 Update Centers on Food, Discounts and Tyres

The clearest competition detail in the notice is the tyre allocation summary. SHIBATA writes that the main-event regulations include the rule and then lists two points:

• Supplied tyres: four tyres.
• Additional purchase: up to three sets, with each set made up of two tyres.

That means the post’s summary describes a four-tyre supply plus a capped additional purchase of six tyres, sold as three two-tyre sets. The post does not reproduce the full regulations, name the tyre manufacturer, state the plastic compound, or say whether the same allocation applies unchanged across every class or category.

For RC drift, those missing details matter. A track’s tyre rule is not just a shopping note; it defines how cars will slide on the event surface and keeps the field on the same grip level. Without the full rulebook in front of us, YAW should not turn SHIBATA’s short notice into a complete technical regulation.

SHIBATA also says it will provide catering service at the event and that discount tickets will be distributed to participants. The post does not specify the catering menu, the discount amount, the vendor or booth where the tickets can be used, or whether every participant receives the same ticket.

Those support details are still worth noting because they shape how an event day works at the pit table. Food service changes what drivers need to bring. Discount tickets can affect when people visit a shop table or parts counter between practice, qualifying and battles. But the limits should stay clear: the source confirms the presence of catering and participant discount tickets, not the full conditions around them.

The same applies to the schedule. SHIBATA says “こちらがスケジュールになります” and asks readers to check it, but the supplied text does not list the times. Anyone attending would need to open the original post and the official event information rather than depend on a secondary summary.

From the material available here, the 2026 GRK最強決定戦 is a competition with main-event regulations, catering and participant-facing support from SHIBATA. What is not confirmed in the supplied post text is just as important:

• the exact event date or dates;
• the venue;
• the track surface;
• the layout and clipping zones;
• the class structure;
• the qualifying and battle format;
• the full tyre rule wording.

For a newcomer, the takeaway is simple: treat SHIBATA’s notice as a pre-event checklist item, not the complete rulebook. The useful confirmed points are the catering note, the discount-ticket note, and the summarized tyre limit. The rest belongs to the official schedule and regulations before a car is set up for the surface.
