Williams will test their updated diffuser and new front wing in Friday's practice at Singapore before deciding whether to press ahead.
Although there are only six races remaining this season, Williams are determined to salvage something from what can only be described as a disastrous season.
The team has scored just five points in 13 grands prix, putting them down in ninth place in the Constructors' Championship.
However, the team is refusing to give up and will head to Singapore with new upgrades for their FW33.
"Singapore has all the challenges, for both the drivers and engineers, of a classic street race, but with the addition of it also being held at night," said technical director Sam Michael.
"There is a large improvement in track grip as the race weekend progresses. There are also more bumps and kerbs to deal with compared to normal and downforce is set to a maximum. Good traction with minimal understeer are always the focus of the car set-up here.
"We have an upgraded diffuser and a new front wing assembly for the first of the flyaways. We'll test both of them on Friday."
Meanwhile, Pastor Maldonado is hoping the updates will give Williams the boost need to achieve a top-ten finish at the Marina Bay circuit.
"Marina Bay is a new track for me so I will need to work hard to learn it ready for qualifying. It will be my first time in Singapore and my first time racing at night as well.
"I really like street circuits so I think I can be quick there. We have some upgrades for this race that we hope will be a big improvement and help us better our last result."
