Round four of the 2012/13 championship will see the series returning to Dubbo for the first time in three years, while Sunday night's fixture will be the first NSSS stopover at Goulburn.

Following the success of the Queensland Cup events before Christmas that produced three different winners from as many races, this weekend's races are much anticipated with teams rested, recharged and ready for the challenge that awaits them.

Particularly exciting for local fans is the fact NSW-based contracted drivers Lachlan Onley and Tony Barklimore head into their home state events on the back of some terrific form from the previous round in Kingaroy last month.

Onley won that event by the closest margin in series history and currently leads the championship, while Barklimore qualified on the front row of the grid and ultimately finished a fine fifth.

Both drivers have been instrumental in ensuring the series' return to Dubbo this season and with their experience on the tight Goulburn circuit, they will be confident of securing strong results at both rounds.

However, the field that has been assembled for these shows is the strongest line-up of Super Sedan drivers at either venue, with the contracted driver line-up boosted by the inclusion of several local and interstate challengers.

Round three in Kingaroy produced a great return to form from two-time series winner Wayne Randall and three-time national champion Michael Nicola, both of whom finished on the podium, edged by Onley in a three-wide swoop under the chequer.

Possessing a wealth of experience and sharing a history of success, the pair will be desperate to avenge that result, start their year in the best possible fashion and stake their claim for the NSSS crown.

Of course, there is a bevy of drivers looking to usurp Onley from the series lead, including opening round winner Matt Pascoe and round two victor Darren Kane, both of whom are former series champions, along with defending series champion Brad Smith and another former NSSS titleholder in Michael Doblo.

While Pascoe and Kane are entrenched inside the top four, neither Smith nor Doblo have featured on the podium so far this season and need a big result this weekend to advance their prospects of a second title.

However, the likes of Dave Gartner and Mark Pagel will be out to intervene and keep their own championship aspirations on track.

Pagel currently sits third in the series standings after a splendid start to his first series campaign while Gartner, who won the only previous NSSS staged at Dubbo, has also been a model of consistency and occupies fifth overall in the championship.

The Dubbo event is proudly presented by Parkes Toyota, Dencol Transport and the New South Wales Super Sedan Association.
