The Haas has been quick at just about all tracks; the Williams has been the opposite. The Williams is having issues with their vortices interaction with the floor when the car changes direction; they are losing down force on turn-in. Haas isn't suffering from that.
They were in Monaco.

"We're missing quite a few parts on the floor and that cost us quite a lot of downforce," said Grosjean.
"Because you don't run a car with this geometry, you don't get the map so you don't know what it does around the corner.
"We would make this thing and put it in a windtunnel to try to find out what it does in yaw, but we lost downforce.
"You guide the air where you want it, and if you take these parts off you don't know where it goes and you're not going to investigate where it goes because you're never planning to run it like this."
They couldn't keep the bits on the car since this area is in line with the floor and any raked car is going to have trouble there.
After they removed the bits in question Haas bargeboards looked exactly like Williams' bargeboards, and their performance suffered. Putting 2 + 2 together leads one to assume that this area is extremely important. It's only reinforced by the fact the fastest cars this year have a very streamlined wing looking version.
