Subaru revealed their Impreza WRX STi Trax at the SEMA Motor Show with some amazing custom work that would be difficult to duplicate. Built for the snow tracks, the Subaru WRX STi Trax boasts 400 hp and was modified by Vermont SportsCar. Originally for famous STi driver Ken Block, the Subaru features a Mattraks rubber track system that comes second to none. The car has a completely gutted interior that was fitted with a multipoint steel roll cage, and seam-welded for extra support. Inside the Subaru Impreza are Recaro SPA ProRacer competition seats, carbon fiber door panels, and a fire suppression system.
