After struggling with brake issues yesterday, Solberg proved day two's biggest winner as he nearly prised fifth off Wilson having been down in ninth position earlier on.
Benefitting from Sebastien Ogier and Gronholm's retirement, the latter caused when he rolled and damaged his Subaru Impreza, as well as an off and a puncture for Evgeny Novikov, Solberg has set his sights on overhauling his team-mate on day three.
The battle for seventh and eighth is close too, Novikov snatching seventh back off Mads Ostberg on the afternoon's first stage, only for the Norwegian to reel him in to be less than a second behind ahead of the final day.
Yet to score this season, it is their position to lose as ninth place Conrad Rautenbach is almost two minutes adrift, while Federico Villagra is a further four minutes off a top eight finish.
Elsewhere, drama continued to afflict the Production WRC class, as Armindo Araujo was able to re-take the lead when Patrik Flodin rolled out of contention on SS12. Together with Eyvind Brynildsen and Martin Prokop losing considerable time on the final stage of the day, the Portuguese man is now more than two minutes ahead of the nearest competition ahead of what could be a famous win for the local driver.
In Junior WRC, Suzuki's Michael Kosciuszko continues to decimate the competition, more than four minutes ahead of Kevin Abbring, who moves up to second in his Renault Clio.
