SCCA® Solo classing — unofficial guide

What autocross class is a Honda Civic (all, 1975-2015)?

HSStreetESTStreet Touring

A stock 1975–2015 Honda Civic (all, 1975-2015) runs in HS (Street) under the 2026 SCCA Solo Rules. Built to Street Touring allowances (within EST tire and wheel limits), it runs EST.

From the 2026 rulebook (Appendix A)

Street: 'Civic (all, excluding Mugen 2008) (1975-2015)' = HS — includes Si of these years. ST: 'Civic (1984-2000)' / '(non-Si) (2001-05)' / '(non-Si) (2006-15)' = EST; 'Civic Si (2002-15)' = DST.
