SCCA® Solo classing — unofficial guide
What autocross class is a BMW M5 (E34/E39/E60)?
FSStreetBSTStreet Touring
A stock 1988–2010 BMW M5 (E34/E39/E60) 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: 'M5 (1988-93, 2000-10)' = FS (no 1994-99 listing). ST: 'M5 (2005-2010)' = BST; 'M5 (E39) (1998-2003)' = DST.
