Which leading team will suffer the most at the Spanish GP from the latest F1 rule change?

As F1 reaches the Spanish Grand Prix for the ninth round of the season, a FIA regulation change comes into force.

The rule, which will see the allowed tolerance of front wing flexibility reduced from 15mm to 10mm, has been scheduled since before the start of the current season.

Despite changes pertaining to rear wings being applied immediately for the season-opening Australian Grand Prix, with further refinements in subsequent rounds, the motorsport governing body gave F1 teams an eight-round grace period, so as to not waste developments made over the winter and to afford the requisite time required to make adjustments.

As a result, there has been significant speculation in the build up to the new regulation being applied from the weekend at the Circuit de Barcelona-Catalunya onwards.

In particular, as the leading team, McLaren has been under a spotlight, as it has also been with recent FIA technical directives aimed at tyre and brake cooling measures, where the Woking squad is known to have an advantage.

The anticipation is the papaya outfit will lose some of its performance advantage when the front wing rules are enforced, but team principal Andrea Stella has persistently played down such talk.

Meanwhile, rival teams, like Ferrari, has suggested it could be a "game changer", as said by boss Fred Vasseur.

Nonetheless, it remains unclear the extent to the impact - if at all - the new rules will have on the pecking order at the sharp end of F1, and if it will have any substantive effect on pace at all.

But it does, however, create an element of intrigue heading into the weekend as to whether any of the top teams will be adversely impacted.
