FSStreetBSTStreet TouringDSPStreet Prepared
A stock 2001–2006 BMW M3 (E46) runs in FS (Street) under the 2026 SCCA Solo Rules. Built to Street Touring allowances (within BST tire and wheel limits), it runs BST.
From the 2026 rulebook (Appendix A)
Street: 'M3 (E46 & E90/E92/E93 chassis) (2000-13)' = FS. ST: 'M3 (E46) (2000-05)' = BST (Appendix A lists 2000-05). SP: 'M3 (E46 chassis)' = DSP.
Unofficial guidance verified against the 2026 SCCA® Solo® Rules — always confirm against the current rulebook before competing. Classing data cites the exact Appendix A wording it relies on.
