Important changes have been made to MSA regulations for underbody protection on historic rally cars following representation from the organisers of the Mintex MSA British Historic Rally Championship.

With effect from 1 January 2017, the limitation on material permitted to be used to protect the underside of historic cars on special stage rallies has been eased. The revised regulation allows for the use of any material of period specification, which removes the previous limitation of fibreglass and opens up the option to use composite material.

The proposal came from discussions within the BHRC management team from the Roger Albert Clark Rally Motor Club and is seen as a move to help keep historic cars competing on gravel rallies.

The ruling from the MSA Historic Committee is as follows:

49.11.4. Any underbody protection must be of period specification. Additionally a guard, moulded closely to the vehicle floor pan, fixed by bolting and/or adhesive may be fitted. It must not extend beyond the front and rear axle centre lines and the outer 100mm on each side must not cover the vertical section of the outer sills.

Reason: To remove the restriction on materials used for underbody protection to allow Historic Stage Rally vehicles to use protection that will be effective.
