Sauber will introduce a raft of upgrades to the C30 for the Japanese Grand Prix in the hope of closing the gap to Force India in the closing five races.
“We will bring a wide ranging aero package for the car, which includes a completely new front wing, new rear wings, new turning vanes and side pod deflectors, new brake ducts and modifications to the floor,” revealed technical director, James Key.
“This was always planned for Suzuka and, if it all works well, it should give us a reasonable step forward,” he added.
The team has suffered in the past few races having only scored a single point in the past four races, compared to 14 in the four previous to that.
“Obviously we want to bounce back from some recent bad luck. Going into the final quarter of the season there will be tracks which should suit our car better. It would definitely be great to get a positive result for all our supporters in Japan in what has been a very challenging year for the people there.”
