This radical, wide-body HQ Monaro build took eight years of exacting work by Down Town Kustoms

WRITING feature articles on cars built by Down Town Kustoms is normally quite a task, as the Taree workshop led by Graeme Brewer has built a solid reputation for constructi­ng genre-busting machines overloaded with cool features. It’s never easy to squeeze all of these little details into a concise story, but I found it particular­ly daunting in the case of Peter Sharp’s SHQRP Monaro, thanks to the sheer scale of the work involved in making this radical, wide-body HQ.

Still, my own profession­al struggle doesn’t compare to the strain Graeme Brewer has felt over the past eight years. “It feels like a weight has been lifted now it’s coming to the end of its build process,” he sighs. “This car has been a massive mental load, because every modificati­on creates 10 other things you need to find solutions to, and there’s thousands of mods, so it extrapolat­es out.”

Coming up with ideas for mad mods is one thing, but working out how to integrate them cohesively into a whole car is a tougher ask.

Building something in a style that hasn’t really been done before is an even spicier burrito to unwrap.

“With a car of this level, there’s no textbook to solve these issues for you, so you just have to think and think and think about it,” Graeme explains. “It just consumes you; I would take it home and it would creep into my brain. It could get stressful, because I don’t always have the answers right there and then.

“These days we know the problems that we will likely face in a build of this stature, and we can fix them before they pop up. But back when we were building this car, we had so much more trial-and-error in the process. Funnily enough, we didn’t have many redos, apart from part of

the floor to accommodat­e the twin three-inch exhaust after the engine stepped up from the naturally aspirated LS1 to the supercharg­ed LSX.”

While it stands as a unique, coachbuilt vehicle today, Peter Sharp’s HQ build actually started off the same way as many others do: Bloke buys car with an idea of a quick tidy-up and repower;

SHIFTING SANDS

ANY car that takes years to build will have some features that will lock it into a certain era, and Graeme is refreshing­ly honest about this when discussing not only the finished car, but his and DTK’S own evolution during SHQRP’S build.

“I’d say this is the car that got us noticed as Down Town Kustoms to start with,” he smiles. “I think it is good to look back at the process of building it, even knowing that, if we built this car now, we’d build it totally differentl­y.

“What I mean by that is our processes have evolved, so we can do it with computer design to speed up the process and increase the precision, plus we’re far more experience­d with cars of this level now. That’s also on top of the parts availabili­ty improving so much in recent years – even things like the HID headlights the HQ has, as they were done before LED headlights were so common.

“There are parts on this car that were so far outside our experience of car building and fabricatio­n when we started, like the rear quarters that Jamie made, but we’ve learned and evolved as a shop. At the time we were building it, all the processes were incredibly advanced. For instance, we made the grille in timber and James Foden had to 3D-scan that, which was almost science fiction at that time, and then it was billet-machined.

“Today, the technology we can build a car with makes these processes far simpler and quicker, so there is no guesswork or trial-and-error. But this car is a good reminder of how we used to work, and how far we’ve all come as profession­al car builders.”

HEADLIGHTS “Every light in the car is LED, except the headlights, which we had custom-made in the USA to match the original size of the HQ items,” Graeme said. “We had this done years ago, a long time before LED headlights were so commonly available. They actually bolt into the same place they’re found on a stock HQ, but people think they’re different because the grille tricks their eye”
TAIL-LIGHTS “The tail-lights would have been one of the first things I did in CAD,” says Graeme. “Initially I drew up original tail-lights but was going to make them slimmer, but the squareness of them dated them badly, so I ended up coming up with this style after mucking around on the computer”
