Even with 911s booming in demand, few will match the price or provenance of this Porsche 911 GT1 Evo soon to sell at a RM Sotheby’s Monaco auction. This is thanks to three things.

Firstly, the GT1 is more racing mutant than 911. Porsche built the 911 GT1 using a carbon monocoque and spaceframe in 1996 to beat up on McLaren and Ferrari in global GT racing, but things turned out less than stellar for it in the first few years.

The GT1 Evo, however, addressed this in 1998, and added aerodynamic aids – namely that rear wing—along with 996-gen headlights as part of the upgrade. Porsche then homologated a run to get its hand stamped for racing.

Take a look inside. Notice no carpet? Or at the engine, notice no silencers? This is not one of Porsche’s Strabenversions (street versions), this is a full gamut race variant, and someone’s slapped a number plate on its rear to make it the only street-registered ex-race GT1 Evo in the world.

With cashed-up collectors out there, expect the GT1 Evo to go quicker at auction this May than it ever did on track.
