SCCA® Solo classing — unofficial guide
What autocross class is a BMW M240i (incl. xDrive)?
FSStreetSSTStreet Touring
A stock 2017–2026 BMW M240i (incl. xDrive) runs in FS (Street) under the 2026 SCCA Solo Rules. Built to Street Touring allowances (within SST tire and wheel limits), it runs SST.
Class by preparation level

A “—” means the car isn’t listed at that level; a build lands in the least-prepared category its modifications allow.

From the 2026 rulebook (Appendix A)
Street: 'M240i (incl. xDrive) (2017-26)' = FS. ST: 'M240i (inc. xDrive) (2017-23)' = SST (ST listing years narrower).
