Radial Tuned Suspension

Ask an Australian car lover who invented RTS (Radial Tuned Suspension) and the answer will be Holden. However, ask an American car lover who invented it and they would likely say Pontiac. In truth, the facts are a little hazy.

In America, Radial Tuned Suspension started in the mid-70s when radial tyres were becoming more of a standard feature on GM cars, and Pontiac tuned the spring rates and shock valving to better match the type of tyres going onto their new cars.

In Australia, the first cars to get RTS were the Holden HZ Kingswood SL, Premier, Wagon and GTS. The HZ hit our roads on October 1977, so from that perspective, the victory goes to our friends on the other side of the Pacific. RTS, according to Holden was “an important new design which integrates all suspension components into one finely tuned system.”

Assistant Chief Engineer Peter Hanenberger from GM Germany headed up the RTS program in Australia and explained RTS was designed to “reduce vehicle roll when cornering, improve straight ahead stability and improve vehicle handling and load carrying ability on all types of road surfaces.”

Effectively it was designed to match all the suspension components because Holden was also moving from bias ply tyres to steel belted radial tyres. Changes included wider wheel rims, revised body mountings as well as the chassis. Front and rear stabiliser bars helped control lean, the four coil springs were deeper, front suspension control arms were redesigned and moved, control arm bushings were reengineered and new, larger diameter shock absorbers were carefully tuned to match the RTS system. All this was designed to create Holden’s claim of “exceptional road holding”.

RTS was so important to Holden, it ran an advertising campaign. It showed a Kingswood SL against a BMW in an evasive manoeuvre display to demonstrate how well it compared against one of the best handling European sedans. A Holden Premier was then pitted against a Mercedes Benz on a bumpy and undulating road, which showed our home grown hero had just as good a ”smooth, flat ride” as its more prestigious and expensive competition.

With the Europeans easily dispatched, the advertisement then turned to Holden’s domestic nemesis. (No prizes for guessing who that might be!) This involved a typical highway exit situation where the RTS equipped Kingswood easily out manoeuvred the competition around a tight bend in wet conditions, showing how predictable the Kingswood SL corners as compared with the other car. That other car, without RTS, was of course unable to follow the Holden at the same speed.

So there you have it. RTS was designed as “a system, through a sophisticated program of engineering research, designed for Australian conditions, so as to enjoy confident, relaxed driving, mile after mile.” Of course, RTS may have been cutting edge at the time, but suspension systems have certainly moved on and will continue to evolve. It’s certainly interesting to see the progress that’s been made over the last four decades of automobile development, that’s for sure. 

Mount Panorama Bathurst

The regional city of New South Wales, Bathurst, is home to the widely renowned Mount Panorama Circuit - one of the most fearsome motor racing circuits in the world. The track, which is a public road for most of the year, holds the Bathurst 12 hour motor race each February and the Bathurst 1000 motor race each October. Mount Panorama is open to the public on non-race days, however if you intend on bringing out your inner ‘Lowndes’, unfortunately a strict speed limit of 60km/h is enforced (sorry!).

Unique in its rural setting, the remarkable track is 6.213km long with a 174-metre vertical difference at its highest and lowest points. In its infancy, dating back as early as the 1960s, the race was dominated by the smaller cars until the development of Ford’s 289 cubic inch V8 Ford Falcon GT. The smaller cars were no match for the big V8 which dominated the Mount on the long up hills and down hills, ultimately changing the face of racing at Mount Panorama forever. Subsequently, manufacturers country-wide attempted to tame the mountain with their vehicles, as success at the track would greatly increase the car’s image and credibility in the Australian marketplace, thus increasing sales.

Ongoing rivalry at this time between Ford, Holden and earlier Chrysler bred the era of our much-loved muscle cars including the Holden Monaro and Torana, the Ford Falcon GT and later GT-HO Super Falcon, and Chrysler's Pacer and Charger. It was also not long after where we were introduced to the late legend Peter Brock, crowned “King of the Mountain” after going on to successfully capture nine Bathurst 1000 victories.

Since 1999, Ford and Holden have lead the pack by miles in the Bathurst 1000, with crowd numbers rapidly increasing each year… and this year was no exception. An enormous 201,416 fans joined the adrenalin rush and excitement of Bathurst, the second highest ever attendance topping last year’s crowd of 195,261!

X Why?

Meet James Mackie. James loves old Ford’s. James also loves drifting. Finally, James loves the Holden V8 LS series engines. What do you get if you combine these three things together?  One crazy XY Falcon.

James would describe himself as a Ford man, but loves all cars.  His previous collection included another XY Falcon, an XW Fairmont and an EB Falcon that he modified with a turbo and drifted over the course of a decade.  He has also owned a VT Clubsport R8, so it is not just all about Fords.

“I’d bought a XW Fairmont for a thousand dollars and then sold it on again not long after, but I regretted not putting the EB Falcon running gear into that XW so I kept a look out for another similar car.

James bought the current Falcon XY you see for $3,000 but his original engine swap idea didn’t turn out as appealing as he had first thought.

“I’m into burnouts, Performance Car Mania, drag racing, drifting and circuit racing so I needed the new car to be a real all rounder.”

“I was going to put the engine and gearbox from my EB Falcon turbo in to the XY, but it was going to be complicated, expensive and require some cutting of the radiator support so I wasn’t keen on cutting up the chassis for an engine swap.

James then spent time thinking through the various other engine options for the XY.

“The two common paths are to build a Cleveland 351 or a 351 Windsor engine, but my budget was limited and to get the horsepower I was looking for (400hp+) I was probably looking at up to twenty thousand dollars to build one properly.

A Toyota 2JZ engine is a super strong engine popular in the drift scene and James even considered this, however it was also going to require chassis modifications so it was ruled out.

James remembered reading about a XY Falcon in a Street Machine magazine that was running a supercharged LS1 engine, so figured it could be an option. However going down this path, James knew he would be (according to some) committing a cardinal sin.

“I knew it was one of Australia’s most iconic cars and it was a hard decision to make, but putting that aside, the LS1 seemed to be the smartest, most practical and cheapest swap available to be able to do all the things I had in mind.”

A friend was selling a LS1 engine and gearbox for only $1,100 which was too good to pass up and very soon the build began.  

“I started by pulling the car down to fix some rust issues and also prepare it for a roll cage.”

 

The cage is very comprehensive and not only stiffens the chassis but will keep James safe in any motorsport discipline he chooses.

New engine and gearbox mounts were fabricated at this time in preparation for the engine. James also purchased some XY floor pan panels, sills and rubber seal kits from Rare Spares to assist in the restoration.

The engine was modified with a camshaft, new valve springs and new oil and water pumps. A custom exhaust system was also produced, before a tune was carried out, which resulted in a solid 370hp at the wheels.

“It took 12 months to build and was a full restoration, without the paint job. I love the rat rod look so the car doesn’t actually look like it has been restored” said James.   

“I nearly had three nervous breakdowns over the build and it really hit home what I had done when I got the car running. Many times during the build I thought ‘what the hell am I doing?”

After unveiling the car on social media and at his first few events, James copped a lot of negative comments which he expected, but after explaining the reason he went that way, most people seemed to come around.  

One of the car’s early outings was at the Calder Park drags where it ran a solid 12.2 second pass down the quarter mile.  

The car remained bulletproof for a year but then things started to go wrong in 2014 when James competed in the Victorian Drift Championship. During Round 1 the wheels studs snapped. At Round 2 the clutch let go and in Round 3 he snapped an axle.

Snapping an axle at Calder Park while going sideways at 100km/h was not part of the plan.

The mid-season drifting festival resulted in a spun bearing so the engine was rebuilt properly with head work and pistons for Round 4. Unfortunately at Round 4 the motor self-destructed. James believes it was something oil related but the engine was so badly damaged he is not sure the exact cause.

Although James is now in limbo with the car’s future, he hopes the next step will be a 6 Litre LS2 with a supercharger, which is the dream.  

A lover of all motorsport, James is keen to have a crack at hill climbs, circuit days and motorkhanas moving forward and the car will no doubt attract attention and divided opinions wherever it goes.

James hopes people can look past the engine swap and just appreciate the car for what it is.

“I absolutely love the car now and don’t have any regrets. I can drive it in just about any form of motorsport. There are not many XY Falcons that can do that and do it well.”

“Nothing is over the top, it has a standard steering box, it still has leaf rear springs and is quite mild to drive. Anyone could take an X series Falcon and do what I’ve done without breaking the bank.”

“I want to thank Mick, Mish, Chris and Dale for all their assistance in the build.  I couldn’t have built it without them and of course my girlfriend Tanya for her support.”

The Rarest Parts

The Rarest Part

As cars age and slowly dwindle from the roads manufacturer support eventually stops producing parts for these vehicles and this is where Rare Spares steps in, providing thousands of parts for all manner of vehicles without part support.

Although rare parts are a speciality of Rare Spares it was time to explore deeper into the world of the Australian parts market. What are some of the rarest parts that exist in Australia?  We asked Rare Spares Director’s to find out some of the extremely rare parts they know of within the market.

A few years back, Director David Ryan remembers looking everywhere for a rubber seal that is at the base of the windscreen divider bar on the FJ Holden.  

“It was a very obscure part and we just couldn’t get hold of one, so we ended up producing one ourselves.” Said Ryan.

Torana A9X ash trays are another random item that are available from time to time, but are at a huge premium.

“An A9X ash tray could go from anywhere up to $1,000.”

According to Managing Director Les McVeigh, FC front fenders and EH bonnets are another two items that are very hard to come by.

“They are not in high demand, but if you were after one, it could be hard to track one down” said McVeigh.

For Rare Spares, some of the most difficult spares to produce are the more modern vehicle body panels.

“The HQ front panel that the grille fits onto was a challenge to get right” said Ryan.

As for the most popular parts, they are often the newly released items that have been produced based on demand from customers.

“Monaro GTS steering wheels have proven to be a popular item as has the GTS rear vision mirrors” said Ryan.   

Rare Spares is happy to look into producing parts as long as there is demand. If you have a query about a part please add your details to the Rare Spares ‘Wish List’.
