The FIA has already addressed uncertainty regarding the manipulation of safety belts which saw both Techeetah and Dragon Racing heavily fined in the last race at Santiago.
An FIA bulletin has been sent to the teams ahead of the Mexico City E-Prix identifying what is not permitted with the new endurance style belts.
This style of safety harness has been implemented since the FIA decided to do away with minimum pit stop times ahead of the Santiago race last month.
The fitting of tie-wraps or the use of tape to the belts will now be deemed an offence in line with any material modification or reshaping to the safety harness.
Both Dragon and Techeetah are believed to have adopted these or similar measures to their cars in Santiago, and both teams were fined a record €15,000 ($18,500) for each infringement.
The implementation of tie-wraps to the lap-straps of the belts is a common practice in endurance racing and allows them to be pulled tighter in a quicker manner.
Additional points were also discussed at the team managers meeting held at the Autodromo Hermanos Rodriguez.
“The FIA has also clarified how, that if you are going to attach and relocate the driver’s radio connector to the seatbelt, you can attach it only to the label on the seatbelt and not through the webbing of the material itself,” Andretti Formula E Team Principal Roger Griffiths told e-racing365.
“We are going to spend some time discussing these points and going through all the regulations around the belts too. It makes sense to tighten down the rules when we are now racing in the pitlane too.”
More detailed checks are set to be carried out by the FIA in this area of the car after the Mexico City E-Prix to ensure such systems are not employed by teams again.
