Taking inspiration from the Dodge Viper SRT10 ACR, the Chrysler Group’s Mopar Underground tuning team applied a similar hardcore treatment to the latest Challenger SRT8 392 before it debuts at the upcoming SEMA Show in the States.

The hard-tuned model is staunchly track-focused but remains street legal and has been upgraded with a range of Mopar performance parts. The new additions include a coil-over suspension, front-and rear-strut tower braces, short-throw shifter, front splitter, cat-back exhaust, custom exhaust headers and a set of Goodyear F1 Supercar tyres.

Mopar Underground didn’t stop there either and made changes to the modern muscle car’s interior and exterior appointments. The car wears white paint with a charcoal coloured roof, there’s a carbon fibre bonnet and rear boot lid, red flame stripes, painted mirror caps and “ACR” badging.

In the cabin it’s all about going light so there’s no rear bench seat and the door panels have been replaced with carbon fibre. There are a pair of bucket sports seats, a three-spoke steering wheel, SRT gauges, custom pedals and the Mopar Drag Pack which includes a carbon fibre centre console. Finishing the track specified updates are a roll bar and fire extinguisher.
