Brock 05 On-line Shop Champions

PETER BROCK,
the General’s Finest Soldier 

Specialist tuning and conversion firms have been part of the European scene, but in Australia such operations have been few are far between.  Barry Naismith investigates our leading example of this specialised business, Peter Brock’s HDT Special Vehicles. 

The Generals Soldier



Getting parking space near HDT Special Vehicles in Levenson Street, North Melbourne is harder than beating Peter Brock at Bathurst.  SS Commodores and other special vehicles, with factory ordering stickers on the windows and pre-delivery plastic protecting interiors, line the street outside the ‘Special Vehicles’ workshop.  Other Commodores cruise the street as part of road testing, but also to find a vacant parking spot.  Still more of Brock’s creations congest the yard at Bob Jane’s Southern Motors, just nearby. 

There is no room inside HDT Special Vehicles and plainly the venture is a great success.  It’s ironic that success has come at an all time low.  While low volume operation like HDT Special Vehicles cannot be expected to be a financial fill up for GMH during hard times, the image building and goodwill generated by Brock’s machines must be considered a priceless investment in a recession rid future. 

HDT Special Vehicles has just celebrated its third birthday.  The operation started rather modestly at Stanley Street, North Melbourne, moved and then moved again to its current address of 12 months.  Both moves were forced by the business out-growing its home.  That problem is rearing its ugly head yet again, but rather than dislocate the business by shifting for a third time in three years, the plan is to make best use of the space and contain its activities.  But another move is definitely on the cards. 

The success of HDT Special Vehicles Pty Ltd shows that the exercise of winning on the racetrack is a great grounding for this type of vehicle.  But also the special vehicle operation is imbued with the same spirit of enthusiasm and dynamism of the Marlboro Holden Dealer Team racing Division, run by Larry Perkins.  The source of that is obviously the dominant personality of Peter Brock, yet democracy works well at Special Vehicles.  Peter’s younger brother Phil gets the title of Manager, Special Vehicles.  He has day-to-day responsibility of managing the Special Vehicles workshop in association with Peter.  This leaves Peter and John Harvey, largely free from workshop detail, to oversee the business side of Special Vehicles and also be involved in the racing area.  All the design idea’s come from Peter, who liaises directly with GMH to see what is practical. 

Apart from the staff involved in Special Vehicles administration and the spare parts shop, there is now about 20 workshop staff, including mechanics, spray painters, vehicle preparers and fibreglass fabricators.  On the premises there is the latest ventilated and heated spray booth, a fabrication area for fibreglass cosmetics and a separate workshop area for the machining of cylinder heads and the modifications of suspension components.  The rest of the workshop space is taken up with cars in various stages of preparation, before going off to dealers. 

The spray painting area is one of the latest additions.  It is an essential part of the operation because new GMH automotive finishes have to be matched exactly and meet GMH’s quality standards. 

 HDT Special Vehicles recently adopted a new assembly procedure for its Commodore SS, a procedure which plugs it even more firmly into the GMH system.
When the operation kicked off, Commodores were built on line at GMH minus the special components and then shipped to HDT Special Vehicles for final assembly by hand.  Then each car was picked up by GMH and delivered to the dealer who placed the order through GMH’s normal dealer ordering procedures.  John Harvey explained that the change was all about shortening the time between the placing of the order by the buyer at the dealership and the delivery, as well as cutting down the labour cost involved in fitting the special components at North Melbourne. 

Until recently, GMH was delivering standard engines to the workshop on a pallet of six.  HDT Special Vehicle mechanics would then change over the cylinder heads and manifold, and then the engines were returned to the GMH assembly line, just like any other engine.  It has now taken a step further with Special Vehicles supplying the SS heads and manifolds direct to GMH for assembly on the assembly line.  “It took us about eight hours work just to change the cylinder heads, “ said John Harvey.  “To do all the cosmetics, interiors and suspension too, it took a long time.  That’s the way it works at the moment.” 

This year HDT Special Vehicles notched up its 1000th car.  At this time however the operation is rapidly approaching 1500 and if all the special orders are taken into account, more than 2000 vehicles have received the ‘Brock’ treatment.  Special Vehicles has produced 520 HDT Commodores, and more than 700 Commodore SSs.  Another 1000 SSs are scheduled to go through the workshop up to next March when a sensational new “SS” is expected to come off the drawing board, to coincide with the launching of the VK model Commodore. 

The workshop is not only brimful of SS Commodores.  A fair percentage of the operation’s work is being taken up with the relatively new Australian Dealer Pack.  This pack, which centres around 4.2 and 5.0 V8 engine modifications, was born out of requests by dealers who wanted something special, but not necessarily a full-bore SS.  This pack and the detailed cosmetic changes that are requested by individuals, is being offered on both Commodore and Statesman. Several hundred of these ADP’s have been churned out so far.  Essentially, the pack involves fitting the SS mechanicals to just about anything from the base Commodore V8 to the SLE and Statesman Caprice.  Sometimes the SS mechanicals are all that is fitted, while other vehicles are also required to be fitted with special seats and/or special wheels and tyres. 

A popular trend developing with the pack is the request for the full SS Group Three treatment on fully optioned SLE V8’s including the aerodynamic body add-ons.  A good example of that was the full treatment recently on a two-tone maroon and grey SLE, skirts, bonnet scoop and spoilers were painted to match the factory colour scheme. 

But while Special Vehicles has been working on Commodores mostly, it has done styling changes and modifications on the whole GMH range, even Jackaroos and Rodeos.  “The car we have received the most publicity out of, because we have produced the most, has been the Commodore.  But we do everything else,” John Harvey said.  The VK successor to the SS should be something else.  It may not be called the SS, but it will certainly be something along those lines.  “There is no point is carrying the SS through three models, when you change a model, you change it.”  John said. 

But while everybody awaits that new sporty Commodore, HDT Special Vehicles is evaluating a limited run of locally made assembled Opel Monza coupes.  Both Peter John spent some time at GM-Opel in West Germany earlier this year investigating the feasibility of such an exotic project.  The intention is to import bodies from Opel in Germany and fit them out with Holden mechanicals including the SS engine and suspension bits.  The ‘mule’ was expected from Germany shortly after Bathurst.  It will be fitted with proper mechanicals and sent out around GMH’s Lang Lang Proving Ground to test it out. 

The popularity of the ADP indicates that there is a strong market for these types of vehicles, especially now that car companies have got right out of the low volume ‘sports’ market themselves.  These vehicles are certainly not cheap though.  A typical up-market ADP pack, for instance, can boost a Holden price tag from say, $25,000.00 to $30,000.00 and that’s big money for a Holden.  “Fortunately there is no shortage of people wanting to buy this sort of car,” John Harvey said.
