At the historical Belgian venue, the Swiss Team-prepared Maserati Quattroporte of Andrea Bertolini cruised to a sensational double win, repeating the team's Donington honours two races ago and trimming the Italian driver's gap to the top in standings to just 10 points.

Luigi Ferrara, who ended up finishing on the podium in both races at Spa, retained the championship lead in his CAAL-run Mercedes C63 AMG, while behind Bertolini, the two manufacturer-supported BMWs of Thomas Biagi and Alberto Cerqui stand in third and fourth places, 36 and 43 points respectively away from the top of the leaderboard.

In qualifying Bertolini took full advantage of his huge experience at Spa-Francorchamps, which includes a string of appearances in the legendary Spa 24 Hours, to clock up a stunning pole despite the wet weather. The four-time FIA GT Champion logged a personal best lap time of 2:52.538 early on, and successfully defended himself from the attacks of several rivals, including his own team mate Alessandro Pier Guidi who wound up as the closest challenger, more than a second back with a best time of 2:53.556.

That left the two red, black and white Swiss Team Quattroportes with a front row of the grid lock-out as third fastest time set by Luigi Ferrara (CAAL Mercedes C63 AMG) was 1.6 seconds off Bertolini's pole time. In addition to the inclement weather, the session was disrupted by a red-flag brought out by a huge fire which engulfed the Chrysler 300C of Mauro Cesari (MRT by Nocentini).

In Race 1 Bertolini prevailed after a tough confrontation with Johnny Herbert (Romeo Ferraris Mercedes C63 AMG), while the Maserati pilot also had to defend himself from attacks by points leader Ferrara. The CAAL Racing driver moved up to second place but eventually had to settle in behind his Maserati-powered rival and was 1.738 seconds back at the flag, while a momentary stutter from Herbert's engine straightened out the picture for Bertolini. The British driver wound up standing on the last podium spot, followed across the line by his Romeo Ferraris team-mates Michela Cerruti and Max Pigoli, and by reigning Champion Thomas Biagi (Team BMW Italia/BMW M3 E92).

In Race 2, Bertolini put together a perfect start-to-finish performance,as he capably held onto his pole position spot and edged Massimo Pigoli's Romeo Ferraris-run Mercedes at the chequered flag by less than 2 seconds. Biagi, Stefano Gabellini (Team BMW Italia) and Francesco Sini (Ferlito Motors/Jaguar XF/R 5.0) rounded out the top-six.

Bertolini's fourth and fifth wins of the season netted him 41 points (20 points for the win and 1 point for pole position) at Spa and it moves him up to 136 points, closing the gap to series leader Ferrara down to just 10 points. The Maserati driver making up for the last round of the season, held at Misano in Italy, where he netted just six points from the opening race. Ferrari meanwhile collected 28 points at Spa. With two rounds remaining to be contested third placed Biagi is still in the title hunt, but is now 36 points adrift and would need to rely on misfortunes for the top two combined with strong results if he is to make a late season tilt at the title.
