A Porsche 911 GT3 RS owner from Florida was able to see his street legal 911 converted into a ferocious 911 GT3 RSR clone while keeping its ability to run on the public roads. This has been achieved thanks to the outstanding work done by Orbit Racing. The converted car benefits from Porsche RSR’s exhaust and a retuned ECU that helps it produce some extra power over the original's 450 Hp. Don't forget to throw an eye on Orbit Racing's site to see the conversion process.
