2019 BingeTokyo Circuit Battle Vehicle Technical & Safety Regulations

Vehicles entering into any BingeTokyo Circuit Battle (BTCB) event must adhere to the regulations of this series as defined within this document; these regulations have been loosely based on universally recognized Time Attack rule packages of various series found around the globe. Regulations are formulated to ensure that all vehicles are properly prepared to a high standard and ensure safety compliance with the series requirements. All points listed will be strictly policed and checked, prior to the starting of each event and any vehicle failing to comply with these regulations will be excluded from the event. The following regulations apply to all BTCB Competitors with specific rules for each class listed separately. 

Any vehicles not conforming may be excluded from any and possibly all BingeTokyo events. If appropriate any/all parts of the regulations may be changed or modified on the BingeTokyo website www.BingeTokyo.jp by the BTCB staff, stewards and technical officials at any time.  Any modifications to regulations made in this way will be clearly marked and reported in the rules section of the BTCB website.

The BTCB rules were drafted in accordance with the BingeTokyo Codes and Regulations. BTCB manages vehicle safety inspection, and in most cases timing and scoring. Your vehicle(s) must meet the basic requirements of the BingeTokyo CCR, found at: BTCB Club Codes & Regulations 2019. As the driver, it is your responsibility to ensure your vehicle will pass inspection. Contact us BEFORE an event should any questions arise. If you arrive and your vehicle is deemed unsafe, it won’t be allowed to run.  BTCB competing vehicles must pass BTCB Tech. No exceptions!

If you are unsure if your vehicle meets the regulation requirements, it is your responsibility to clarify any/all areas or points prior to an event (or of equal importance, before tearing into your car.) Please address any technical questions through the BTCB Race Steward via email to info@bingetokyo.com

If the discrepancy is deemed intentional under classing to avoid safety requirements, the competitor will be disqualified and will not be allowed to compete.
