Williams technical director Sam Michael says the team is targeting a double top eight finish in the Japanese Grand Prix this weekend.

The team will introduce the final upgrade onto the FW32 at Suzuka as it seeks to build on the double top tens secured at both Monza and in Singapore.

With Rubens Barrichello having battled to a fine sixth place on the Singapore streets, Michael said the team was heading to Suzuka in confident mood with the top eight positions firmly in its sights.

"Suzuka is a high downforce circuit with a figure of eight layout," he said. "The track has it all, but one of its highlights is the fantastic Esses section. Being able to deliver a strong sector time across that part of the lap is one of the best indicators of a driver's ability.

"Both cars will be running our final upgrade components and we expect to run them all weekend. Our target will be for both FW32s to be fighting for points among the top eight contenders and to therefore be racing for points."

Like many of his rivals, Barrichello said he regarded Suzuka as one of his favourite circuits on the calendar and said he was optimistic of a strong weekend from the team.

"I love going to this race, it's in my top three of all the tracks we visit," he said. "It's a big effort to get there, especially from Brazil, but you quickly forget about that when you engage first gear and leave the garage for the first time. Suzuka is a lovely circuit. It's a very high speed track and has lots of high speed corners. You really have to be on it all the time.

"I'm fortunate enough to have raced in Japan since 1993 and it's wonderful to keep going back. We will have to wait and see how we go but I am optimistic that we can do well again this weekend."
