SCCA® Solo classing — unofficial guide

What autocross class is a Lotus Emira?

SSStreetSSTStreet Touring

A stock 2024–2025 Lotus Emira runs in SS (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: 'Emira (all) (2024-25)' = SS. ST: 'Emira (V6) (2017-26)' = SST (listing years odd — verify).
