Porsche 997.1 GT3 Racecar For Sale
This racecar is truly one of a kind. Starting its life as a 997.1 GT3, over the past five years, it has experienced a complete transformation into a fully dedicated racecar with no expense spared.

Add to that Bosch Motorsports M5 ABS, dual brake master cylinders, and 380 mm Brembo brakes in all four corners, and you get the full performance package. Oh, and it only weighs 2,775 lbs without driver…
