If you haven't heard of the Ringbrothers yet have a passion for muscle, we suggest educating yourself at your earliest convenience. Much like tuning firm SpeedKore, this is an outfit obsessed with making old-school metal cooler than ever. The tuner has also worked on some modern machines, but the people who work there have a particular affinity for classic muscle. Over the years, a number of outstanding creations have left the shop, but the latest may eclipse all that came before it. Named CAPTIV, this is a Dodge Charger like no other, and as is fashionable, it packs a Hellcat crate motor with 707 horsepower.

Mated to a six-speed manual transmission from Tremec, the engine powers the rear wheels with the aid of a carbon fiber driveshaft from QA1. Other highlights include custom HRE wheels, Baer six-piston brakes, and Michelin Pilot Sport 4S tires. MoTeC handled the engine management and gauges while Flowmaster provided the custom exhaust system that exits aft of the rear wheels. But as cool as all these parts are, the finer details truly blow you away. Custom-made billet indicator stalks are just a taste of the billet parts throughout the build and are joined by aluminum pedals and an exquisitely retrimmed cabin with loads of leather and a pair of customized Recaro seats. The highlight of the interior has to be the carbon fiber steering wheel though, boasting billet aluminum spokes and hub and a 3D-printed horn button.

The car was built for New Zealand motorsports legend and TV personality Greg Murphy, who had the car disassembled and prepared before shipping it to the States for the overhaul. Here, it was subjected to between 800 and 1,000 hours of bodywork that included making the Challenger a unibody and finishing it in a unique interpretation of Porsche's Signal Yellow, here renamed Pile Up Yellow. The paint has four base coats in white before yellow was applied and topped with six coats of clear. This was then polished to a mirror finish and looks amazing from any angle. Combined with the perfectly centered hole in the hood, the aluminum instrument cluster surround, and just the overall finish of the build's multiple components, we think this could be the best amalgamation of old and new muscle yet.
