The Ascari KZ1 has been adapted for racing, primarily being featured in the new FIA GT3 European Championship and the used United SportsCar Championship as well as other smaller national series which run a similar formula. These cars, known as the KZ1-R,are similar to the KZ1, but vastly improved. The most obvious differences between the KZ1 and KZ1-R lie on the exterior of the car. Tuned for racing, the KZ1-R is still a pure road car in every right, but with the invigoration of a GT3 racer. The front lip spoiler has been updated with a pronounced splitter for increased down-force. Also unlike the KZ1, the race version features a larged fixed racing wing, in place of the small spoiler. The headlights have been stripped down to the essentials, with HID bulbs and turn signals, losing the silver and crystallized look of the KZ1. The rear fenders of the car have also been increased slightly to house the larger wheelbase. The wheels are forged aluminum alloy, to further reduce curb weight. The interior of the car has been completely stripped. Power windows and seating have been removed. Fine leather is replaced by alcantara, cloth, and carbon fiber racing seats. Much of the interior is made of carbon fiber, and what isn't is either plastic or aluminum. Replacing these creature comforts is and integral roll cage, which adds rigidity to the car's body during races. The KZ1-R is stripped its luxury but not without a benefit. Curb weight is reduced to an astounding 1250 kg(), which is helped by its carbon fiber monocoque chassis and body shell. Ascari plans to only produce 50 specimens of the KZ1-R model.[3]
