The issue first surfaced in the porpoising technical directive issued by the FIA ahead of the British GP, which detailed plans for stricter monitoring of ground flex.
The TD also gave details on how the governing body would use an aerodynamic oscillation metric, or AOM, to measure porpoising and bouncing.
The new requirements were to be imposed on the French GP, after two research races in Britain and Austria.
However, after discussion at the F1 Commission on Friday, it was confirmed that the application of the TD has been postponed to Belgium, the first race after the summer break.
In the meantime, there will be further discussion on the final wording in the Technical Advisory Committee.
Curiously, Mercedes boss Toto Wolff says he would have preferred the TD to be applied to the Paul Ricard, as originally planned.
“I wish it had happened immediately,” he told Motorsport.com. “Because it can impact performance. And so now it’s fine, just say good, that’s it.”
Speaking earlier to Sky, Wolff had made it clear that he thought some rivals were taking advantage of the ground flex.
“I think so,” said the Austrian. “I failed to tighten the skates of certain teams. We look at our competitors.
“And probably, I would have liked the TD to come a little earlier, but that’s how it is. So at Spa, we won’t see that again.

Horner clarified that the TD’s primary purpose is swing monitoring, something his team hasn’t suffered as much as their rivals.
“The technical guideline is obviously focused on the bounces and porpoises that some cars have struggled with,” said Horner. Sky F1.
“I think it is necessary to discuss further in the [TAC]which is the right forum for this.
“Obviously we saw that at Silverstone, no car was really affected by it. The argument being, is it the competitor’s duty to make sure their car is safe, or is it the duty of the FIA to ensure that the competitor uses his car in complete safety?
Regarding Wolff’s suggestions on flexible flooring, he said, “That’s rubbish. Total waste. I think we are mixing issues here.
“Maybe he’s referring to, I don’t know, the cars around him at the moment. I have no idea, but I have absolutely no issues or concerns on our floor.
Red Bull Racing’s chief engineer Paul Monaghan said that, like their rivals, the Milton Keynes team should consider the demands of the TD.
“I don’t think we can ignore it, it would probably be a bit naïve of us,” he said when asked by Motorsport.com.
“Some new constraints are applied. We haven’t had the data from Silverstone for a long time to see how our interpretation compares to that of the FIA.
“So we’ll start with that. And then whether or not we are more effective than others is really up to others to determine.
“The only thing we can control is our two. And if we change, adopt and respect the FIA AOM criteria, that’s our job done. The trick for us will be to minimize this if there are changes that are needed that cost you performance.
“Otherwise we have to keep doing what we are doing and keep the car as fast as possible. It’s a judgment call against our opponent rather than an outright lap time for us.”
Meanwhile, AlphaTauri technical director Jody Egginton doesn’t expect to see a significant impact on his team.
“I mean, we think we’re comfortable with the metric at the moment,” Egginton said.
“We’ve been monitoring it, it hasn’t raised any alarms for us in terms of what we have to physically do to the car to meet the demands of TD. A few hiccups, but I don’t go in not in details.
