KW Suspensions provides the revised, two-way racing dampers that can be adjusted for damping level and ride height without removing the wheels, and a stiffer front anti-roll bar increases roll stiffness. Tires are the track-spec but street-legal Michelin Pilot Sport Cup race rubber.

The interior is largely stock Viper, but for those who want to add even more lightness, an optional “Hard Core” package deletes the audio system, the underhood silencer pad, the trunk carpeting, and the tire inflator. In the radio’s place is a panel where one can mount a lap timer, which Dodge throws in for free. The end result: another 40 pounds lopped off, bringing the weight reduction to a total of 80 pounds.

And there’s still plenty to shock and awe on the exterior. The ACR’s signature paint scheme is a wicked two-tone featuring a black hood, trunk, roof, and wheels, with a choice of bright red, blue, violet, or orange fenders. A driver stripe in fender color is available as an option, but we think it’s absolutely necessary.

The front splitter has a swappable front aero-track extension and a pair of dive vanes rendered in exposed carbon fiber. Together, they are said to help increase front downforce by nearly a third. And of course no track-day special would be complete without a rear wing that could have come from a Cessna, also rendered in carbon fiber.

The Viper ACR is scheduled to begin terrorizing U.S. streets in the second quarter of 2008. It will make its public debut at this month’s L.A. auto show.
