A stock 1984–1991 Honda CRX 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: 'CRX' = HS (years approximate; listing has none). ST: 'CRX' = EST. SP: 'Civic & CRX (1988-91)' = CSP; 1984-87 = FSP.
