As always, competitors and officials at Round 4 of the Independent Race Series were in the running to win some great prizes from Kumho Tyres.

The winner in the Production Racing Cars class, with the prize for this round going to the winner of Class X, was Franck Donniaux. Franck wins a pair of Kumho race tyres.

And the volunteer official drawn out of a hat was Wayne Johnson from Goulburn. Wayne worked at the event as a flag marshall, and wins a set of Kumho road tyres.

Kumho helps the Independent Race Series recognise our hard working officials, with one randomly chosen at each round to receive a set of Kumho road tyres. To find out more about being an official for the Independent Race Series, click here.

The Independent Race Series hosted its most successful round ever at Sydney's Oran Park on the Grand Prix layout on the weekend.

Record fields in a number of categories boded well for the event before it even started, and the spirit of the competitors, and quality of the racing all added up to make it a great weekend of racing.

Action got underway on Friday (14 August) morning, with unofficial practice. Qualifying kicked off after lunch, and the first of the races were held late Friday afternoon. The weather was perfect throughout, and Saturday morning brought more sunshine, and plenty of racing.

Muscle Division saw the inclusion of HDT Cup at this round, and some great racing. The outright honours were dominated by Stuart Inwood in his impressive Nissan R33 GTR Skyline. Inwood was victorious in three out of the four races, only missing out on the handicapped Race Three when his handicap proved too huge to overcome. Brett Morse (Mazda RX7) was also impressive, taking second outright for the category. Third outright was Greg Boyle (Nissan). In the sub categories, Rod Gurney was top Muscle Car, Merrick Malouf was the winning Ute, Todd Betland took out Saloon Car honours, Steve Berry was the best of the Improved Production cars and Stuart Inwood also took out the Japanese Turbo category.

In HDT Cup, there was plenty of action, and Adam Lloyd emerged the outright victor for the weekend. He won from Adam Tipping and Keiran Macklyn. In the sub categories, Troy Harrison won Class B Classic and Keiran Macklyn won Class A Classic. The HDT Cup proved to be a massive success, with the combination of affordable machinery, a recognisable brand, and close, fair racing proving very popular!

In the Production Racing Cars, there was an upset at the front of the field. Anthony Soole has had the upper hand all year, with Franck Donniaux plagued with reliability issues at earlier events. Not so this time out though - despite some VERY close racing, Donniaux (Subaru WRX) took a clean sweep of wins to end up victorious in Class X. Soole (Lotus Exige) secured second in Class X, with Daniel Flanagan (Commodore Ute) taking third in his first run in the car.

In Class A, Clark Stott (Mazda 3 MPS) proved too good, to take the class honours over Geoff Kite and Hans Riehs.

Class B was very nearly a family affair, with Carly Black (Peugeot 206) fighting it out with father Barry Black (Peugeot 306), Neil Byers spoiled the party though, pushing his Mitsubishi 380 to take class honours ahead of Carly followed by Barry.

Class C was another family affair, husband and wife duo John and Kylie Willmington taking on the class in a pair of Nissan Pulsars. John dominated the category (outdoing a number of higher classed cars), ahead of Chris Reeves (Proton Satria) and Josh Riehs (Proton Satria). Kylie did very well on her debut though, finishing fourth in class, and just one point behind third!

Formula Tasman & LeMans Sports saw a promising field, with some truly exotic machines fighting it out. Chris Farrell brought along his beautiful 2001 Swift Formula Atlantic, and was never headed all weekend, the car looking planted on the track, and Chris driving very nicely. Farrell took out the Formula Tasman win, and outright victory. Ed Singleton pushed hard in his immaculate Singletini Radical, taking the LeMans Sports honours. The placings in each category were: Formula Tasman - second Craig Dawson (F391 Dallara), third Chris Lynch (F397 Dallara); and LeMans Sports - second Andrew Macpherson in the formidable Mosler MTR, third Neil Kenny (Mallock MK31).

The Touring Car Challenge saw a diverse field do battle, with some excellent racing, and plenty of spectacle. Andy Cantrell in the ex-Glenn Seton Falcon V8 Supercar was untouchable throughout the event, taking pole and victory in two of the races, to take the outright victory. Close behind though was Dameon Jameson in his awesome Jaguar, who took two race wins, and second outright. Third outright went to Joe McGinnes in his crowd pleasing XT GT Falcon. Class honours went to Cantrell for V8 Supercar, Phil Groeneveld for V8 Giant and Dameon Jameson for Muscle Car.

A welcome addition on the card at Oran Park was the MX5 Challenge. The large field of these nimble machines joined the RocketSports ranks, and enjoyed two standalone races. In the RocketSports outright, the MX5's proved unbeatable, with David Raddatz taking the victory. He was closely followed by Matilda Mravicic, and Nick Martinenko. The Holden Roadsters mixed it up with the MX5's, putting on a great show. Graham Smith ended up on top in the Roadsters, with Rod Moynahan second and Terry Mayfield third.

In the MX5 Challenge, honours in the Turbo category went to David Raddatz, in the NA Slick category, Shane Otten took the win, and in the NA Road category Corey Stevens took the honours.

Overall, the whole meeting was a huge success, and thanks must go out to everyone who helped make it happen - the outstanding competitors, new and old, the volunteer officials and marshalls, Oran Park management and of course the hardworking iRace team.

The next confirmed event for the Independent Race Series will be held at Oran Park (South Circuit) 13-15 November. The team are working hard on securing an event in October - details will be announced as soon as they are available. We're working hard to keep bringing you our trademark brand of mate-against-mate, affordable racing.

Round Four kicks off in just over 12 hours, and it's looking like the biggest iRace meeting yet.

The round, to be held at Sydney's Oran Park, on the GP layout, will feature racing by all the iRace categories: Formula Tasman & LeMans Sport, Touring Car Challenge, Muscle Division, Production Racing Cars and RocketSports. Additionally, the round will see the debut of the brand new HDT Cup category, and the inclusion of the MX5 Challenge.

The Independent Race Series prides itself on mate against mate racing, and catering for a diverse range of competitors and cars. This round will feature a number of notable competitors:

Andrew Macpherson will be driving the awesome Mosler MT900GTR (pictured right) in the combined LeMans Sports and Formula Tasman category. He'll be up against lady racer, Michele Guyer in her March Formula Holden and Ed Singleton (who made quite an impression in Muscle Division in his last appearance) in his Radical. Chris Farrell will driving his 2001 Swift Formula Atlantic, which should suit the GP layout very well. The Formula R boys are also back, and always push hard.

In the Touring Car Challenge, Darren Saillard will be the man to beat, but Andy Cantrell (pictured left) will be looking to do just that, after being narrowly defeated at the last outing at Oran Park. Friend of the series, David Towe will take the wheel of the ex-John Bowe Mustang, and will no doubt adapt quickly from his light BMW M3 to the hulking V8 Mustang. Steve Ingwersen will be keen to make an impression in his Commodore V8 Supercar, and Joe McGinnes is always spectacular!

RocketSports will be joined by the MX5 Challenge for this round, with nearly 20 of the nimble handling Mazdas in the field. The Holden Roadster brigade have been working on the handling of their cars, and Rod Moynahan, Clive O'Connor, Graham Smith and Terry Mayfield (pictured right) will be battling it out. The MX5 Challenge will also have two standalone races on Saturday.

The Production Racing Cars category has gone from strength to strength. The affordable and accessible nature of the machinery, and the closeness of the racing has really driven that growth, and this round looks to be the biggest yet for the category. Pushing hard for a great result will no doubt be Anthony Soole. He'll be challenged by Richard Mork, an Oran Park expert. Hans Riehs always goes hard, and will be doing double duty this weekend, driving his BMW Mini as well as a HDT Cup car. The girls will be well represented too, with Carly Black doing a great job in Class B, and Candace Shafell returning to Class C. Kylie Willmington (picutred left) will be making her debut in a former championship winning car. Kylie's husband, John is currently leading the Class C championship, and we've received some inside information that Kylie will give John a serious run for his money. Kylie has secured support from Caltex Depot, Jax Tyres Penrith and Penrith Muffler Man, and will be driving a Nissan Pulsar.

And last but by no means least is Muscle Division. Muscle Division will feature the largest field at this round, and will incorporate the brand new HDT Cup category. Muscle Division has seen RX7s run strongly in previous rounds, but they are yet to take a round win - Alex Hay, Gerry Murphy, Brett Morse, Keith Linnell and Steve Anslow will all be looking to rectify that this weekend. Previous round-winner Howard Glinn will be back in his Dolomite Sprint, and watch out for a round long battle between him and Neville Simmons like we saw at the last round. The big story of this round though is the HDT Cup. A category that was only conceived after the last meeting at Oran Park in May, HDT Cup has generated massive interest, and sees a massive TWENTY cars entered for the first outing! Watch out for strong performances from Todd Betland (pictured right), Hans Riehs and Chris Reeves, and the no doubt numerous dark horses, new to the series.

Round Four of the Independent Race Series is just over one week away, and the excitement is building about the return of iRace to the fantastic Oran Park venue.

Entries have been rolling in for the event, and it's looking like some healthy fields will be in attendance, the standouts being Muscle Division and Production Racing Cars.

In Production Racing Cars, most of the guns from Round Two are back, and this time out they'll be joined by Graham Lusty in an XR6 Turbo Falcon, and Bryan Fitzpatrick will return in his nimble Renault Clio. Look out for some hot action from this group.

Muscle Division has been swelled by the inclusion of the HDT Cup within the ranks, with plenty of excitement and enthusiasm surrounding the new category. Perhaps one of the most excited is Todd Betland. His Commodore (pictured right and below) has been decked out in Peter Brock colours and livery. Aside from being a gun racing driver, Todd once starred in a Fair Dinkum Sheds commercial alongside Peter Brock. Todd's HDT Cup car is a fitting tribute to the Australian motorsport legend.

Todd will be joined by a number of other competitors who are still waiting for the paint to dry on their racing machines, including Robert Marchese. Robert's car (pictured left) still has some finishing touches to be completed, but he is very keen to get on track.

Other categories in action will be: Touring Car Challenge, Formula Tasman and RocketSports.

The full round schedule will be available shortly. Round Four of the Independent Race Series will take place on the GP layout at the Oran Park venue, with action kicking off 14 August, and concluding 15 August. More information on the round is available here.

For spectators admission will be free. For competitors, entries are still open, so if you want to enjoy this awesome venue, get your entry in asap.
