The Balance of Performance heading into next month’s 24 Hours of Le Mans has been released, with weight and power adjustments made to all cars since the FIA World Endurance Championship season-opener at Spa.

It comes following the planned rollout of a Le Mans-specific BoP for the event.

While all cars have been given power reductions and weight increases, the Aston Martin Vantage GTE has been hit the least, with only a slight reduction in turbo boost and a 5kg increase in minimum weight since Spa.

BMW’s new M8 GTE, which also struggled in Belgium, has received 13kg of additional weight and a slightly larger power reduction when compared to the Aston.

Both the Aston and BMW are now at 1268kg, compared to the Ford GT’s 1280kg, after receiving a 25kg increase and turbo boost reduction since Spa.

The Ferrari 488 GTE, meanwhile, also faces a similar power reduction to the Ford, although has only been given 11kg of weight.

Porsche’s 911 RSR will head to Le Mans with a 0.6mm smaller air restrictor and a 17kg increase in weight, with the Corvette C7.R set to run at a minimum weight of 1244kg and a 29.5mm (x2) air restrictor.

Fuel capacities have also been adjusted across the board to limit the maximum stint length to 14 laps at Le Mans.

Per the bulletin, “teams cannot do more than 14 laps in any conditions” while also will be limited to 35 second refueling times via its own declared refueling restrictor.

The same stint length enforcement is in place for GTE-Am, although refueling times must be 45 seconds.

Power Reductions Also in GTE-Am

GTE-Am competitors, meanwhile, will also face a class-wide reduction in power for Le Mans.

Both the previous-gen Aston Martin Vantage GTE and mid-engined Porsche 911 RSR have been given 0.6mm reductions in air restrictors, with a slight boost decrease for the Ferrari.

Additionally, the turbocharged Ferrari has received a 4kg weight break after struggling at Spa, with the Porsche given a 4kg increase.

It’s unclear if the BoP changes to GTE-Pro would extend beyond Le Mans and into the third round of the WEC season at Silverstone in August, as the bulletin states the adjustments are applicable “until further notice.”

Changes, however, can be made following the Le Mans Test Day on June 3 and into race week itself, although last year’s Le Mans-specific BoP was declared for the event only.

BMW and Aston Martin have been among the manufacturers pushing for a reset of the auto BoP system.

    So whos got the list of overall weights?

    • Old Trombone

      May 22, 2018 at 10:19 am

      I was gonna write exactly the same question. Weight change info is good, final weight numbers would also be good. Doesn’t change the fact that SC365 is still the best SportsCar site of all time!!!

      • John Dagys

        May 22, 2018 at 10:25 am

        Here is the weight breakdown:

        Aston – 1268 kg
        BMW – 1268 kg
        Corvette – 1244 kg
        Ferrari – 1291 kg
        Ford – 1280 kg
        Porsche – 1259 kg

          John, thanks for posting these, do you have a link to the FIA webpage with the full BoP tables or bulletin? Thanks in advanced

        • David Chaste

          May 22, 2018 at 12:41 pm

          So in conclusion the ferrari is the best car ever. They have the most weight and over the years the 488 has had the smallest fuel tank of all in fia and imsa. Yet it stays competitive.

          I still want an american car to win, but it’s impressive from ferrari.

          • Thomas

            May 22, 2018 at 1:28 pm

            How they manage to have a better turning car compare to the ford gt with its full carbon chassis is beyond my understanding. Even the fuel consumption, a turbo V8 should consume more than a V6 turbo, right?

            Realy hope they can find a close BOP and have the capacity to sanction the sandbagging teams.

          • AudiTT

            May 22, 2018 at 4:00 pm

            The 488 is the base car. Everything else is BoP’d up/down to it.

          • bjones

            May 22, 2018 at 8:43 pm

            Usually the V-8 will get better mileage than the V-6, with all other things being the same, such as displacement. It has to do with size of the piston and fuel mixture. That is the best I can explain it. Some of the thick glasses wearing guys could either do a better job explaining it or confuse us all.

            American cars have won! The Corvette has the MOST consecutive wins since the C5…..

      There’s going to be more changes after the test day.

    • David Chaste

      May 22, 2018 at 12:43 pm

      Corvette has a lot of reduced power.

  3. NASCAR/DPs Suck

    May 22, 2018 at 11:36 am

    I don’t understand the lap restriction for GTE Pro. I thought it was stupid to do this to LMP1 to appease Toyota but now to apply this same logic to an all pro pure factory category is even dumber.

    • Pierre G. Joly

      May 22, 2018 at 5:30 pm

      Strangulation by regulation

    • JEZ

      May 22, 2018 at 6:05 pm

      They’ve always tried to have the lap and fuel restrictions, it’s just that they did it by managing fuel capacity and fuel flow restirctors. Instead of trying to get all of that right, it is easier to just say you can’t run more than XX laps and you can’t fuel quicker than XX seconds and let the teams worry about those details.

      They still have the tank capacity but now have a fall back in case they’ve gotten in wrong. They can give up on the fueling rig restirctor all together.

    Is Brian France secretly running the FIA WEC this year?

  5. Radon

    May 22, 2018 at 12:21 pm

    Limiting lap count and fuel fill times now too? So many regulations.

    • Bird

      May 22, 2018 at 5:55 pm

      That’s always been regulated.

  6. jason

    May 22, 2018 at 12:32 pm

    What lap time do you think will be pole for GTLM at Le Mans this year then? Any shot at the mid 3 min 40s?

    • JEZ

      May 22, 2018 at 6:01 pm

      Right now the cars are all actually a little slower than last year (except maybe Porsche) so it is hard to see the lap times being that low. I’m sure most cars will find a little speed from last year just because they have a year’s worth of development, but no one is finding 4-5 seconds.

  7. fourloko

    May 22, 2018 at 12:48 pm

    takeways so far

    WEC ford gt heavier and less boost than imsa
    WEC corvette 4kg heavier but smaller restrictor than imsa
    WEC bmw 40kg heavier, ~0.2 bar less across the board boost than imsa
    WEC ferarri 25kg heavier, ~0.1 bar less boost than imsa

  8. David Chaste

    May 22, 2018 at 12:55 pm

    Limiting lap counts, and refuel times is to try to keep the gte pro cars behind the p2 cars. Aside from maybe 4 or 5 p2 cars, all gte pro cars have better overall lineups. If the well heeled folks in p2 really bin it, and the lmp1 cars are unreliable they hope not to have a GTE Pro car on the overall podium.

    • Mike S.

      May 22, 2018 at 2:53 pm

      Oh yeah they have better lineups than p2. Porsche 4 cars with all the factory boys and Ford 4 cars with factory boys. I believe that the fastest car doesn’t always win in these events. As it should be in a 24 race there is weather, and luck and bad luck and happenstance. #912 Porsche probably wasn’t nor should of won N24 without the help of their faster and stronger Manthey car #911 crashing. The #912 wouldn’t of won after being down many minutes to the Mercedes if it wasn’t for the 3 hour delay and red flag for heavy rain that took away that 3 minute gap. That is endurance and yes BoP all day and the fastest car per say isn’t guaranteed.

      • mike

        May 28, 2018 at 11:58 am

        “Wouldn’t of won?” of?

    • amg gt

      May 22, 2018 at 5:08 pm

      Are u kiddin?? P2s have almost 600hp and are a lot lighter,never seen a P2 ending up behind a GTE,given a trouble free race for both

  9. Robert

    May 22, 2018 at 2:21 pm

    Here’s an idea for BoP – stop the nonsense. Or as the expression goes – shut up and race.

    It’s this nonsense why I don’t really follow this racing that much. Set the rules for everyone at the beginning and everyone runs to the sake rules. No handicapping this team or that team. That’s not racing. Racing is the fastest car/driver/team wins. If the only way you can win is because the fast guys are hobbled, that’s not a race, that’s not a win.

    I would rather see a blow out season where one team honestly dominates than a fake season of fake wins. And if a team is a blowout winner one season, then fix the rules for next season. But in the meantime run the rules you started with and stop trying fabricate preferable outcomes.

    • Robert

      May 22, 2018 at 2:25 pm

      One more thing. If you want rules that tightly control everything then go Formula racing, there’s a place for that. This is supposed to be SPORTSCAR racing. Stop promising sportscar racing then run it (rules) like a formula series.

      • AudiTT

        May 22, 2018 at 4:04 pm

        These are mass produced GT cars (OK, Ford is an exception). Without BoP everyone would need a mid-engined, turbo car, with small frontal area, to be competitive.

        Before BoP we basically had turbo 911’s and Vipers in the old GT2, and a fleet or RSR’s and 360’s in the GT3 of the day.

      • Andy

        May 22, 2018 at 6:53 pm

        And blatant misunderstanding of what a formula series is, well rather was. It’s a formula not a specific set of regs, there’s FAR fewer regs and changes in F1 and SuperFormula over any sportscar series. F2/3/4 are all spec or restricted as is Indycar with small exceptions so I wouldn’t say those have counted for years.

  10. Dave

    May 22, 2018 at 2:47 pm

    Good God. I hope they don’t ruin this race. BoP the cars and then let them race – cars, drivers, TEAMS. Strategy – especially in a 24h affair – is as interesting as a great pass or laying down the fastest lap. Don’t regulate that out of endurance racing.

  11. Roger Gantry

    May 22, 2018 at 2:51 pm

    BOP was a stupid idea from the start. Suppose to give exiting and close racing but all it did it made races a procession . Watch GT3.It is difficult to overtake because all the cars have the same performance and if you do manage to pass there are usually accidental contact for which you are penalized

    • amg gt

      May 22, 2018 at 5:12 pm

      Probably you have NEVER watched a Blancpain endurance race…

      • Roger Gantry

        May 23, 2018 at 6:17 am

        Actually I have been following races for the past 50 years and keep record of 28 championships I raced myself at several European circuits and know what racing is about. I do not just sit behind a computer and criticize people who give their oppinion

        • Roger Gantry

          May 23, 2018 at 6:30 am

          Just to add to this I attended the races at Brands Hatch and Silverstone and did not watch it on Tv

          • amg gt

            May 23, 2018 at 3:59 pm

            And what you raced? you may have seen thousends races probably the wrong ones. Again,have you ever seen a Blancpain Endurance race? Look at the gaps of the last one at Silverstone,and may be,just may be,you can change your mind.

          • amg gt

            May 23, 2018 at 4:03 pm

            Advising someone to watch something is a criticize??

    • Bird

      May 22, 2018 at 6:06 pm

      Lol having similar performance has nothing to do with over taking. Having too much down force decreases over taking.

      • Andy

        May 22, 2018 at 6:56 pm

        Having too much poorly designed downforce limits passing. You can have downforce cars and passing but you need to lower to cars and let the diffuser and floor work harder.

        GT3s have a tough time, at times, with passing from poorly used tracks without space. Watch anything in a small tight course, hot lap qualifying is great, racing terrible. Modern GTs need to stretch their legs and leave behind nonsense like Macau

  12. JEZ

    May 22, 2018 at 4:45 pm

    Had to do a quick compare to last year’s Le Mans BoP because changes from Spa aren’t that helpful on the high speed low downforce Le Mans.

    From last year’s Le Mans (looked quickly so forgive any errors)

    Corvette: 1 KG heavier, same restrictor
    Ford: 12 kg heavier and a minuscule boost reduction
    Porsche: 9 KG heavier and a .2 mm restrictor opening increase (so should probably be a little faster than last year)
    Ferrari: 23 KG weight increase, and a little boost increase. Note the Ferrari has an evo kit, so it isn’t the exact specs of last year, who knows what that means for on track performance)
    BMW: New Car
    Aston Martin: New Car

    • Jake

      May 22, 2018 at 6:56 pm

      Thanks for that, I was more curious how it compares to last year. Seems logical to me. Aston had the best performance with last years car, no idea how the new car will fare. But guessing Spa wasnt entirely accurate (leaving a reserve for the sake of competing at LM) Corvette, Ford, Ferrari and Porsche should all be right there. And BMW with the new car as well is unknown.

    Whatever happened along the way to lose sight of may the best design win or be fastest? The BOP leaves me absolutely stone cold bored with the whole of top level sports car racing. I think vintage racing is more fun with its noise and narrower tires and sliding around. I get it, the need to attract and keep manufacturer interest by manipulating the chance they can win. How many deals are made behind the scenes to guarantee every make some wins, keep them coming for commercial reasons? I am disgusted with the whole arena.

    • Dave

      May 22, 2018 at 6:20 pm

      I think if it was just Le Mans, that should be the plan, bring your best car within the spec and race to win. With a series though it would be unwatchable if there was one car per class that dominated each outing. It’s a long way to next season if you are ceding 3-4 seconds a lap to the competition from event #1. BoP is or the sake of making a season competitive.

    • Andy

      May 22, 2018 at 7:02 pm

      How many of the builders of those vintage cars exist? How well did Lola do after building dog after dog of a car after F1 drained their cash? Where did Lotus end up? MG? There’s plenty of old cars in history that bankrupted their owners trying to race until you ended up with just a few. Those who have survived aren’t going up race a dog. And if you think most are building poor cars and hoping for BOP to speed them up. Well actually poor example since it seems like Aston and BMW have decided to that a lot here lately. But Ferrari, Porsche, Corvette and yes even the “Ford” GT at least try to build a good car on its own merits.

  14. Paul

    May 23, 2018 at 4:58 am

    Anyone know if the weight creep over the years is intentional or just happening somehow? Not long ago the base seemed to be 1245kg and BOP gave certain cars less than 1200kg with this being the “haviest” year yet: 1244-1291kg

    Coming soon homologated air, homologated toilet seats for the bathrooms, homologated drivers cloned from Alain Prost (they wouldn’t use Micheal Schumacher as he is not French), homologated rain provided by a dome and sprinkler system at random times, and homologated sunshine via an orbital sunshade.
