Former Bathurst 1000 winner and New Zealand racing legend Greg Murphy has unveiled his 1969 Hellcat-powered Dodge Charger, built by The Ringbrothers.

The Charger has been in the build for quite some time at The Ringbrothers workshop in Wisconsin, undergoing extensive work.

The Ringbrothers is headed by brothers Mike and Jim Ring, who specialise in building world class street machines and a swathe of high-end aftermarket components for classic American muscle cars.

The car arrived to The Ringbrothers workshop as a rolling shell a few years ago. “We’re excited that we had the opportunity to build this car for Greg,” said Jim Ring.

“Pretty much every part of this car is custom, although we really wanted to just scream Charger without being heavily modified,” said Mike.

While the supercharged Hellcat crate engine is nothing to snort at, it’s the attention to detail to the body, metal, paint and interior work which really sets this Charger apart.

The Ringbrothers extended the lower sill to give the car a more aggressive and lower look, sitting on top of a one-off set of HRE wheels, wrapping in massive 345-section Michelin rubber at the rear.

The floor and transmission tunnel were built to accommodate the exhaust and the Bowler Performance six-speed manual ‘box.

“(There’s) close to 800-1000 hours of bodywork into this car,” said Mike Ring.

Four coats of basecoat went down, followed by six coats of clear. The sanding process progressed from 600 grit sandpaper to a super fine 5000 grit before a final buff.

The unique yellow was chosen by Murphy. “Greg came up with it, it’s a Porsche Signal Yellow and I absolutely love it on the car,” said Mike.

Finishing off the exterior are custom made indicator lenses in the lower section of the front end, as well as the Hellcat blower poking through the bonnet. “We couldn’t have the bulge of the supercharger off to one side, it just didn’t look right,” said Jim.

“So we made another one that centres the nose of the supercharger,” said Mike.

The interior is just as detailed, put together by Steve Pearson from Upholstery Unlimited. The seats are a pair of beefed-up Recaros, with a dash displaying data from the MoTec ECU system and a one-off steering wheel.

The wheel was designed and made in-house by the Ringbrothers, who now plan to make the wheels available in their parts catalogue: “If you can’t find something that works, just build it,” said Jim.

Murphy is a true car tragic, who posted his admiration for The Ringbrothers on social media.

“Mike & Jim Ring and the entire @ringbrothers crew have made the build such a friggin awesome experience and have overdelivered at every step of the process. I cannot thank you guys and girls enough,” he said in the post on Instagram. “Just a tad excited right now to see this thing in the flesh.”

The Charger joins an impressive list of machines in Greg’s garage, which includes a HSV VF GTSR W1, an all-out Holden Barina rally car and a recently restored two door Ford Escort Mk2.
