The FIA has made additional Balance of Performance adjustments to GTE-Pro class machinery ahead of next weekend’s 24 Hours of Le Mans, with changes to four of the five cars in the factory driven class.

Outlined in a bulletin issued on Thursday, the latest change sees the Le Mans Test Day pace-setting Corvette C7.R slowed, with a 0.3 mm air restrictor reduction.

The Porsche 911 RSR, meanwhile, has been hit with a 5kg minimum weight increase, with the Ford GT receiving a further 5kg weight reduction, on top of its 20kg break it received prior to the test.

Aston Martin’s 2016-spec Vantage GTE has been given the biggest adjustments, in the form of a 10kg weight reduction and 0.2 mm smaller air restrictor.

Fuel capacity levels have also been adjusted across the class, with the Aston now eligible to carry 102 liters, compared to 98 liters for the Ford, 95 for Porsche, 93 for Corvette and 88 for the Ferrari 488 GTE car.

Per the revised BoP, the Aston must also run “Aero Kit B.”

No changes have been made to GTE-Am, other than a refueling restrictor increase for the Porsche.

The changes are only in effect for Le Mans, with the previous BoP table set to serve as the base for the remainder of the FIA World Endurance Championship season.

    Another Ford weight break. Shocking. 55lbs in a week! Should have sponsored by Jenny Craig.

    Is the ACO pulling these dataloggers and actually analyzing the data, or just looking at lap charts and flipping a coin for weight or restrictor change based on the running order. It feels an AWFUL lot like the latter.

    If Ford had a troubled race but fought with difficulties themselves, it would be a great comeback even if they had finished far from podium. But with all that ridiculous favouritism from ACO it becomes a stupid advertising for their prototype. Somebody should tell ACO that this is too obvious.

    ACO has already bended its own rules accepting the Ford which is a prototype and not a genuine GT. A mockery. They will do everything to have the car a winner.

    We’ve come to expect this kind of constant manipulation of car performance from IMSA, but why has the FIA adopted the philosophy? The Ford has not shown to be disadvantaged to this point by anything other than what could be considered new car development issues, so why the adjustments? If Ford had been flogging the life out of the car to keep pace for multiple events then you look at the BoP, but the Ford only has 2 previous races on its WEC resume.

      I think two adjustments as a quantity is fine for Le Mans, just like for Daytona. They’re unique tracks with a mandatory test day, so if you’re getting it right that means a pre-test and a post-test adjustment.

      It’s the direction of the changes that’s the issue here. Ford did not appear to be in need of cornering help, and already seemed to be the fastest in a straight line.

        Ford was fastest in a straight line. They needed help in reliability! Now the ACO is trying to out do the IMSA. They are killing racing! The isle of Mann TT does it right,put them on a Dyno run by officials with knowledge and its simple X HP = X weight. Since the Isle implemented this the racing is much closer. It puts in it the hands of drivers not officials!

    It’s almost as if they want the headlines of a Ford win. I hope they get blown away when it comes race time.

      No, not the ACO. I’m shocked that you’d imply they’d ever do something like that! What’s next, saying that they’d favor a French manufacturer at Le Mans by turning a blind eye to their driving standards?

    25 kg total for Ford? Wow. At this rate they can soon add a riding nechanic!

    Well its all set up for Ford to win. Now the ball is in their court and make sure they have reliable cars and its all theirs to win.

      As a fan of the GT, I sure hope all you guys are proven correct 😉

      If they really have been sandbagging all year, it’s an amazingly well orchestrated and coordinated effort, look at their test day times, virtually identical across the 4. It’s a new level of playing the system if true, and that’s pretty impressive in its own way.

    The ACO is really committed on ensuring that a Ford wins the race. I expect the Fords and the F488s to be in the order of 1.5 seconds per lap faster than the RSRs which just received a weight penalty. The Astons even with the restrictor penalty will be in the mix in terms of ultimate lap pace. We shall see in a week’s time.

    This is like Audi at Spa 2014. Everybody got a weight penalty or restriction right before the race

    Now I really want the Fords to break.

    Remember, Chevrolet and Porsche have no factory teams in the FIA WEC this year. Ford does. So with FIA sanctioning the 24 Hours of Le Mans, they have a greater desire to see Ford win as opposed to IMSA’s top two.

    A greater sign of an ever-growing rift between IMSA and the FIA-ACO sad reality forming friends.

    I wonder how much kickback IMSA got from Ford for this fiasco. Ford have been absent from GTLM for decades and needs to put every effort into becoming competitive with the other GTLM long-term participants. Even if Ford wins at LeMans, I wonder how many $450,000 cars will be sold. Didn’t they read the Viper saga? Go Team Corvette!

      There’s a waiting list for the 200 Ford GTs being built per year. Dodge was trying to sell closer to 1,000 Vipers per year, and their price point was a much more crowded market.

    I’ve been a Blue Oval fan since a small child so I am rooting for them but I hate BoP in every sense of the premise, always have. I will enjoy a win immensely but wish FIA (and IMSA) would let these boys race. IMSA took all the technical advantages away from P2 to the point of embarrassment, its ruining our sport. Stop it already. #realtechwins

    wasnt the 06 gt in gtlm for a while? whether it was factory or privateer teams…and BoP changes arent just willy nilly, they use telemetry iirc

    And I thought IMSA was bad. Don’t go out and work your butts off,the ACO will help you,welfare for the Fords! I’m turning off the race now! Its no longer the best at what you do and how you do it. The teams that work the hardest get penalized the most! PLEASE GM,pull out of the ACO and IMSA,it does you no good. Go SCCA racing and be done with it!

    What happened to build the best you can and you will be rewarded. The Corvette GTLM program is the best on the planet. I guess the French are going back to being French. Kiss Ford’s Ass and screw everyone else. I can’t believe these teams,GM/Ferrari are just going to bend over and take it. They can appeal these changes if I am not correct? Help me on that one! it takes all the fun out of it! No Le Mans for me this year. TURN OFF FOX S1
