Force India know they need to get out of their current slump if they don't want to suffer a major financial setback.
After challenging McLaren for fifth place in the Constructors' Championship during the early stages of the season, the Silverstone squad have gone off the boil since Pirelli made changes to their tyres.
They are now sixth in the standings and have Sauber breathing down their neck after Adrian Sutil and Paul di Resta picked up only three points between them in the last seven races.
Force India deputy team principal Bob Fernley warns that losing out on sixth place will cost them dearly in terms of financial payouts from prize money.
"The difficulty for us is we are still off the pace of where we were," he told Press Association Sport.
"That is opening up the door for Sauber who have had some very strong races, and now we are really looking over our shoulder.
"I know everybody thinks it's easy, but once these results start to come in, the traction you get is considerable.
"Most of the gaps in prize money (in the Constructors') are between £3.5million to £4million, but unfortunately the gap between sixth and seventh is more like £6million to £7million.
"So it's a big hit, not one we want to be taking."
Force India are currently 17 points ahead of Sauber, who are on a good point-scoring run the moment, and Fernley hopes they can maintain that gap in the final four races of the season.
"We can chip away at where we are to try to get back into the points, and we're almost there," he said.
"We just have to try and find a little bit more. If we can get that extra tenth (of a second) or two then it allows us to compete, but whether it will be enough to compete with Sauber, I'm not sure.
"But then it wasn't a good day for the top teams - Lewis (Hamilton) retired, (Nico) Rosberg had a drive-through (penalty) - so that automatically propels people up.
"To a certain degree we need the top teams to stay where they are."
