Drivers are reminded that as per regulation 231.19.03, the new BriSCA F2 / SSCA specification crankshaft speed sensor housing MUST be used in place of the original Ford component on ALL cars from 17th May 2025. From this date, the minimum/maximum air-gap regulation will be removed, as per the wording in the current note in the regulations. The regulations will be updated prior to the 17th May to reflect the change.

Note: From 17th May 2025, a standard BriSCA F2 / SSCA specification crankshaft speed sensor housing MUST be used in place of the original Ford component.

• The BriSCA F2 / SSCA spec. housing must NOT be altered in any way.
• It is permitted to shim the speed sensor when mounted to the BriSCA F2 / SSCA spec. housing to take account of variations in length and voltage strength of permitted aftermarket sensors. The necessary air gap to the flywheel with the BriSCA F2 / SSCA spec. housing is therefore dependant on the sensor in use, and not a fixed sized.
• There is no restriction on the shim thickness used for the speed sensor on the BriSCA F2 / SSCA spec. housing… it should be shimmed as required.

It is permitted to use the new BriSCA F2 / SSCA specification crankshaft speed sensor housing with immediate effect, if so desired, subject to the above.
