Technical Updates from MSUK
Seat Life for events which require 'in date' FIA seats - March 2021 - 1yr Extention
The applicable Regulations are N6.13.6.1 and R48.10.6, and the extension applies specifically as follows:
Seats with an original homologation label detailing a manufacture date during 2013, which may be used for up to 8 years from the date on that original homologation label;
and
Seats with a ‘Not Valid After’ date (on the original homologation label) of 2019, which may be used until 31st December 2022.
The validity dates above take into account the additional two years’ use over the FIA homologation validity already afforded to seats used in National Events in these disciplines.
The date of implementation of the above Exemption (Regulation A2.4) is immediate and will cease on 31 December 2022.

Seat Mountings – Dec 2020
Further amendments have been made to the seat mounting regulations in (K)2.2.1, these amendments give further detail to the requirements for transverse seat mounting rails.
These new regulations are only a requirement for new build cars from 01 January 2021. They are not to be retrospectively applied to existing cars
Seats, Seat Belts and Headrests – Nov 2020
New rule
K2.1.12. Elastic devices attached to the shoulder straps are forbidden. Date of Implementation: Immediate
Reason: Elastic devices attached to harness shoulder straps to aid egress are a safety concern as they may pull the shoulder straps off the FHR. The regulation copies an FIA regulation which prohibits their use.

Road Rally Tyre Rules (also applies to Targa Rallies)
N.B. Always check event regulations which may put in place additional requirements. For example events in Wales require E marked tyres, whilst this remains a very rare rule outside of Wales.
