Mark Webber has warned his rivals to stop trying to find fault with Red Bull and concentrate on resolving their own issues.
Red Bull's latest design concept, the front wing, has come under considerable scrutiny, given its flexibility at high speed when it is supposed to remain static.
Ferrari have also developed their own version, and although no team has lodged a protest, there have been many complaints, despite the wings passing the current FIA tests.
Mercedes team principal Ross Brawn has, however, claimed the tests are "not correct", and so, ahead of the Belgian Grand Prix at the end of the month, they are to be improved.
But after Red Bull's innovative exhaust-blown diffuser was also frowned upon before rivals caught up, championship leader Webber feels the criticism is all a lot of hot air.
"Our guys have broken their balls to design a car in the spirit of the regulations, and every time we are tested by the FIA, we pass," said Webber. "We've turned the world upside down to try and do that which is not without resource difficulties, but that's Formula One.
"We're more than happy with what we have on the car, and we're sleeping well at night. You should never penalise things that are ingenious, and people who are doing a good job."
Webber feels if the critics want to harp on about parity, then Red Bull should be allowed to equalise their engines in line with other teams.
At present, the Renault powerplant is down on horsepower compared to the likes of Mercedes, as used by the German manufacturer, McLaren and Force India.
Webber added: "We've been looking for engine parity for the past few years because we know we don't have the most powerful engine. Other teams sometimes want everything, but we need parity on the engine and then it would be a fair game. That's all we want, similar horsepower to other teams."
