    I recently started doing races by the license, this way I can get most of the major races done and out of the way. So I finally got up to 25 percent and discovered that there's an A License endurence race, Laguna Seca 200 Mi. for those of you who need a refresher. So I start to race it using the BMW M3 GTR racecar that you get as a prize car and I'm killing them.

    So then, my tires start to lose wear and I'm forced to pit and I fall all the way to first place. Is it just me or do the other cars seem like they are cheating? Has any one been able to figure out what kind of tires they are using or do I just have to pit the same time as some of the other cars just to keep my first place?

    To check what tyres they're using, before the race, do a preview. The titles show what tyres are being used.

    Pit when you need to pit, and don't bother pushing too hard into the orange, it could well cost you more time if you spin than you actually save. :yuck:

    As far as strategy goes, this is part of the fun of enduros. Depending on the race, I usually find I have to pit about 2/3rds of the way through the AIs stint, so I have to go fast enough to make up 30 seconds (ie 1 pitstop) in every 3 stints. As long as each time you leave the pits you are further up the field than you were the last time, you should be on target.

    It's worthwhile figuring out a strategy where you don't have to pit in the last 3 laps (except at the Nurb) as that could easily lose you the race if it's a close one. ;)

    There are many ways to kill a cat, and just as many different strategies to win an endurance race, so prepare to be confused... :confused:

    Have fun! :sly:

    I would have thought so, since it was my closest competition when I ran this race.
    I don't actually own a 787B yet in GT4, so I'm not sure what it's like. From the way the AI drives it, I'd say it was lighter on tyres than other LeMans racers, and therefore less frequent pitstops should make up for outright speed. I think either route_66 or jdw has tried out the 787B, not sure if it was the used black one, or the new 4,500,000 race version. I'd try PM-ing them and see what response you get.
    Good luck if you try it! :tup:

    Thank you SmallHorses! I think i'll start LAST 24 hours (Le mans I) by next month when i have enought money, and i don't think i wanted that black because it's old and have many miles on it, so i might lose control or something (just like my write-up 2 or 3 months ago). but i agree with you that it have better tires wear. i'll let you know when i will start 24 hours le mans

    I'm sorry to bump an old topic, but I noticed that the Mercedes 2.5 Evo II Touring Car was listed as pitting every 4 laps. This isn't true. I B-Specced the race 3 days ago and he pitted every 5 laps. The Opel Calibra Touring Car and Alfa Romeo 155 Touring Car pitted every 4 laps.

    There are some discrepancies in when the AI pits certain cars, and it seems that it varies by AI lineup and the car that you enter. Prime example is the difference seen in the pit strategy of the Spoon Integra at Motegi 8Hr. It's been reported between 11 laps and 23 laps by different folks.
    Personally I've not run any of the enduros more than once yet to test if the AI pits are consistent, but its something I'll be looking into in about 51.5% completenesses (if that's a real word :p!!!) time. That may take a while though!
    All of Extreme hall to do yet & its still not unlocked!!! :crazy:

    Dodge Viper GTR Oreca (didnt check, wont be competitive) - simialr to the chev


    Im racing in a STOCK Black R390GT1 on S1/S1 tires

    with the chev in the field i still got 200pts
    with the GT40 in the field i got 176pts

    Excellent information CBR250RR!

    I may create a special post for all the pit strategies for all the AI cars in all the enduros, later on, but it'll take some time to do, especially for Sarthe and 'ring enduros, this is a great headstart for Fuji though!

    Tsukuba 9hr is already complete.
    Fuji 1000km is 95% complete from the post above.

    Keep the entries coming, even if they're not 1st or last to pit entries, every pit entry for any of the cars is welcome for any enduro, as it'll help me to compile the list sooner rather than later!

    EDIT: just read post #43 - you already have this info, but have not updated post #1

    I am currently racing in the Tsukuba 9hrs Endurance where for the first 6 hours the Mazda RX-7 Spirit R Type A pitted every 35 laps which is about exactly as far as I can push my Lotus 111S - it has been a close race. The RX7 has started pitting a bit earlier in the 7th hour - don't know why, it will probably cost him dearly as we were both on track to make only 13 stops but he will probably now need 14.

    Sorry, I'd kind of given up on this thread in favour of the more comprehensive thread that's stickied at the top of the Race Reports Forum. I'll add your info in there, and a credit to you in post #1. Check it out!
    :cheers:

    *edit* Yeah I just checked post #43, and it's my own edit,:dunce: after I auditioned a ton of cars to get a good close race for Tsukuba 9hr and in the process found the pit strategy for every AI entry, thanks to jdw's list! If you're interested, you can find my amazing 29s MOV report after 9 full hours of racing here!:eek:
