LATEST UPDATES TO APPENDIX K
Following the last World Motor Sport Council meetings, an updated version of Appendix K has been published and will be applicable from 1st of January 2022 with the following amendment being adopted:

HOMOLOGATED CARS – Appendix K – Article 7.3.3
Following the work achieved by the Historic Technical Working Group through the FIA archives, a list of corrected minimum weights for specific homologated cars reflecting the publication of FIA Bulletin n°43 of January 1, 1971, and applicable from Period G2 will come into effect.

TYRES – Appendix K – Article 8
As per our previous newsletter, the updated version of Article 8 for tyres is now incorporated and will be applicable from 1st of January 2022. However, the homologation procedure remains ongoing and further details will follow during the first trimester of 2022, ready for the start of the season.
As detailed in the regulations, the Historic Technical Tyre List will provide all the acceptable products for the Vintage (FIA Period C to E included) and Historic (FIA Period F) range.

CONDITION TESTING – Appendix III
Further work achieved by the Historic Technical Working Group to bring Appendix III up to speed with the current specific standards and requirements for condition testing for suspension components. Housekeeping which we hope will help the community.

SPECIFICS – Appendix VII – PORSCHE 901/911
Addition of a clarification for the use of timing chain tensioners on the Porsche 911 engines from 1964 onwards.

TECHNICAL REGULATIONS FOR FORMULA JUNIOR CARS – Appendix XIII – Article 4.4
As detailed since its publication at the end of 2019 and with a two-year notice, adjustable spring platforms will not be acceptable for Period E Formula Junior cars. This is applicable to current Historic Technical Passports and any new application and/or renewals.

Any indication of when and where will we be able to see a revised tyre list?

The tyre list will be published on the FIA Website before the start of the season and information will be sent to promoters and clubs.

I can see that there is now the option of an alternative to Dunlop Historic tyres with the addition of the Continental/Hoosier tyre. However, so far I've not managed to find any way of acquiring such tyres.

Anyone any ideas?

Ditto.

Thanks Duddha for the information and link.

Comparing the prices quoted in Germany against the equivalent sized Dunlop Historics (albeit from the UK price list) appears to indicate a 40% premium for the new tyre. Unless someone can demonstrate a significant advantage over the Dunlops (i.e. in the quality) I think they may struggle.
