SpeedART Porsche 911 SP91-R Car Concept is based on the 911 Carrera Utes, and it includes each drivetrain and aerodynamic upgrades. Changes to the engine include a full manifold-to-tailpipe sports exhaust, optional variable seem valve for the exhaust, and the ECU remap offering an increase associated with 25 horsepower – taking the total for you to 425 horsepower. The speedART SP91-R bodykit for the 911 Carrera Azines includes a fresh rear wing, rear diffuser, side skirts and a front spoiler. Your rear wing is designed to be mounted on the original rear spoiler and present additional downforce at speed. Additional upgrades for the speedART Porsche 911 SP91-R consist of massive two-piece forged alloy 21-inch wheels, different suspension systems – which include both track and street choices – and an airlift suspension system to increase the vehicle’s practicality. On the inside, speedART have assaulted their own 911 SP91-R show car with a poorly thought out custom leather and Alcantara combination. The lime green using royal blue stitching might be a crime in opposition to subtlety, but thankfully speedART will tailor the car to virtually any colors you like.
