It’s surprising how a few tweaks can turn the polarizing style of the Honda Civic sedan into something with an abundance of visual appeal. Unveiled at the 2006 Chicago Auto Show in concept form, the 2007 Civic Si sedan wears aggressive 18-inch black alloy wheels fitted with 225/40 performance tires, large cross-drilled disc brakes with painted Brembo calipers, and a body-color rear spoiler. Our eyes feasted on the rubber crammed into and pushing the outer boundaries of the wheel wells, though the production version will surely sit a bit higher, allowing for more daylight between tire and car, not to mention a less punishing ride. The hood looks to be composed of tuner-favored carbon fiber, yet in reality is simply painted black.
