A. Cars may compete with FIA or FIA-Approved Test Houses homologated cages provided the cage was built by the manufacturer or a manufacturer designated shop/team and approved for use. Cars must have the FIA identification plate attached to the cage along with a letter from SCCA Technical Services certifying the origins of the car, or confirmation that the cage was certified by an FIA-Approved Test House.

B. Cars may compete with an approved MSA (Motor Sports Association UK) Roll Over Protection System Certificate. All related engineering drawings and documents shall be submitted to SCCA Technical Services. Cars must have MSA identification plate attached to the cage along with a letter from SCCA Technical Services certifying the cage was approved by the MSA.

C. Cars which do not comply with the design criteria set forth for roll hoops must have a waiver/homologation certificate issued by the Road Racing Technical Staff. Cars which are excepted from the published design criteria, shall at all times have available for examination a current logbook, a copy of the letter of exception from the Road Racing department and supporting engineering documentation. Cars which have previously been issued homologation Certificates may satisfy this rule by presentation of said certificate or a copy. Vehicles with an SCCA logbook issued before prior to January 1, 1983 do not require homologation certificates.

Note: This line primarily applies to those who own older SCCA road racing cars or factory-built racecars that probably had a previous history with the SCCA or other sanctioning body. While the Road Racing Technical Staff can evaluate and approve another design, the far easier (and less expensive path) here is to build it to the published specs. If you have an older formula car or sports racer, it should have a homologation certificate that goes with it.
