“Following the recent findings on the functioning of the new front fairing mounting kit, homologated as from 1 January 2015, the CIK-FIA has decided to immediately suspend the use of this kit for an indefinite period. Tests are currently underway to clarify the criteria for a definitive solution.
As of now and until further notice, the homologated front fairing mounting kit as defined in Article 31 of the CIK-FIA Specific Prescriptions must therefore no longer be used. Front fairings must be fixed non-removably pending the outcome of the tests and the validation of a new kit. Only the front bumper support – the central part of the homologated front fairing mounting kit, which secures the bumper bars – is now usable. Front fairings homologated for the 2015-2020 period must be used with a fixed mounting.
For further information, please refer to the CIK-FIA Bulletin No 40.”
