Following a fax vote by the members of the World Motor Sport Council, the regulation (Article 255A, Appendix J, 5.1.1.b) relating to the size of the restrictor in the 1.6 litre turbo-charged Super 2000 car has been confirmed as 30mm. This applies to all such cars competing in 2011 FIA Regional Rally Championship events.
This regulation is intended to balance the performance of cars powered by 2 litre normally-aspirated engines and 1.6 litre turbo-charged cars.
