Price On Request 1997 Porsche 911 GT1 Straßenversion considered to be one of the best examples for sale PORCreated to homologate Porsche's 911 GT1 contender, the street version, sometimes called 'Strassenversion', is one of the most fierce and rare 911s. Apart from the sparse interior, little differentiates the GT1 from the full-on, race-ready counterpart. The homologation regulations demanded that the car complied to both the rules of the road and track. This included comprehensive European regulations which created a golden age of GT1 racing.The GT1 was based on the 993 body shell, but with modified exterior panels and a substantial roll-cage that also supported the engine, gearbox and suspension. This helped Porsche avoid necessary crash testing and reinforced ties to the production cars.While the first version of the GT1 debuted at the 1996 season, Porsche only produced a single homologation car. The following year, the 'Evo' version was released with new kidney-shaped headlights and improved aerodynamics. This was good enough for Porsche to build twenty examples for select customers.
