The all-new ’12 Civic Si can be seen at the head of the pack at IZOD IndyCar races. The venerable Si was breathed upon by Honda Performance Development (HPD), Honda’s racing division. HPD decided to leave the Si’s new 2.4-liter, 201hp inline-4-cylinder untouched but focused heavily on the brakes, adding 4-piston calipers, competition rotors, racing brake pads and stainless steel brake lines. Other mods included Enkei rollers, Firestone Firehawk rubber, Sparco seats, 4-point Sparco racing harnesses. The exterior received a Honda body kit and substantial decal action.
