Formula One's top teams are reportedly ready to remove their Front and Rear Interconnected (FRIC) suspension systems for the German Grand Prix amidst growing doubts unanimous support for delaying a ban can found.

Autosport reports Red Bull, Mercedes, Ferrari, McLaren, Lotus and Williams are among the outfits willing to support a pact to not protest rivals for running FRIC for the remainder of 2014. This would appear to end suggestions that the issue was raised to the FIA as a plot to slow Mercedes, who are thought to have one of the most effective FRIC systems.

But it appears other outfits are not as eager to support that pact, suggesting they could be prepared to report any rival which arrived at Hockenheim running FRIC. The punishment for any offender in that circumstance may be exclusion from the results.

An FIA technical directive was issued to the teams following the British Grand Prix warning that cars running such systems could be reported to the stewards, though it stated FRIC would remain on the cars until the end of 2014 if teams agreed unanimously. In the wake of that directive Autosport reports that most teams carried out the two-day test at Silverstone this week without their FRIC systems.

FRIC systems link the front and rear suspension to help control the pitch of the car under braking and maintain its ride height for aerodynamic advantage. They have been run by several teams in recent years, but were first developed in F1 by the Lotus team.

Final confirmation on the stance of the other teams is not expected until next week.
