Force India will introduce a major car update at this weekend's Spanish GP with the new aero package fitted to both cars.
Like many of their rivals, Force India will head to the first European race of this season with updates for their car.
The Silverstone team, though, are believed to be set to introduce some of the biggest changes as they look to improve on their P8 in the Constructors' Championship.
Speaking about the new package, team boss Vijay Mallya said: "It’s on schedule to be fitted to both cars ahead of Friday practice. It’s pretty comprehensive and the car will look quite different."
Upgrades, though, are not all Force India need.
Last time out in Russia only one driver, Sergio Perez, reached the chequered flag as Nico Hulkenberg was booted into retirement on the opening lap.
"I hope we’ve used up all of our bad luck already!" Mallya added. "We’ve yet to see how we perform in a clean, trouble-free race without safety cars, red flags or accidents.
"Despite not realising our potential in Sochi, we took encouragement from our qualifying and race pace: the car is improving and we’ve got a good base on which to build.
"There are 17 races to go and I’m confident the best is yet to come. It’s a marathon, not a sprint."
