The rules requiring Rally2/R5 cars to run in homologated specification came into force from 01 January, having been passed in September 2024 with a year’s grace period given.
Please note that this also includes the requirement to run a 32mm restrictor and a homologated pop-off valve in accordance with FIA Technical List No. 43 (which is available to view by clicking here).
For confirmation, the only modification from Homologated specification permitted for this vehicle type is a right-hand drive conversion. Please familiarise yourself with the National Competition Rules Ch.13 App.16 Art.4.2.a and Ch.13 App.24 Chart 50.
Note that this is an evolving situation, and there is likely to be further detail introduced into the National Competition Rules in collaboration with the Rallies Committee, so please keep an eye on the Proposed Regulations WhatsApp channel and Regulation Changes for Consultation page on the website. We will also share any relevant guidance via this bulletin.
