SCCA® Solo classing — unofficial guide
What autocross class is a BMW 3 Series (E9x, non-M non-turbo)?
A stock 2007–2013 BMW 3 Series (E9x, non-M non-turbo) runs in GS (Street) under the 2026 SCCA Solo Rules. Built to Street Touring allowances (within DST tire and wheel limits), it runs DST.
Class by preparation level
| Stock (Street) | GS |
| Street Touring | DST |
| Street Prepared | — |
| Street Modified | SM |
| Prepared | FP |
A “—” means the car isn’t listed at that level; a build lands in the least-prepared category its modifications allow.
