The kit consists of wider front and rear fenders, new front and rear bumpers, hood and side skirts. The new pieces will be built out of lightweight carbon fiber and Kevlar fabric and have been developed by vacuum forming. Each customized Carrera will come equipped with a set of ultra-light ADV.1 forged wheels. Expect the TopCar kit to debut at Top Marques in Monaco come April where further details will emerge. Despite being larger than the model it replaces, the latest Carrera is 143 lbs lighter. With a 350-horsepower 3.4-liter inline-four, the Carrera 4 will hit 60 in 4.7 seconds, while the 400hp, 3.8-liter Carrera 4S drops that down to 4.3.
