GSStreetGSTStreet TouringSSPStreet Prepared
A stock 2015–2021 Subaru WRX (VA, non-STI) runs in GS (Street) under the 2026 SCCA Solo Rules. Built to Street Touring allowances (within GST tire and wheel limits), it runs GST.
From the 2026 rulebook (Appendix A)
Street: 'WRX (non-STI, excl. TR, tS) (2002-26)' = GS. ST: 'WRX (non-STI) (2002-25)' = GST. WRX STI (2004-18) = DS street / BST. SP: 'Impreza WRX (incl. STI)' listings = SSP.
