Hot on the tail of our news on the Dodge Viper SRT10 last week comes this monster, the ACR (American Club Racer) 'Hard Core' pack. This beast still uses the same 8.4-litre V10 as a normal SRT10, as if it's not enough, but has been tweaked to develop 448kW.
A carbon fibre spoiler kit, including a rear spoiler which has seven levels of adjustment, will increase down force by up to a third and has also managed to reduce overall weight by 18kg. Non-essential components have been stripped out of the car including the radio and carpet.
The Hard Core pack goes on sale after the Los Angeles Motor Show at the end of this week.
