    Hey everyone,
    I wanted to share an update with you all. After some consideration, I’ve decided to step away from the Porsche 935/K3
    leagues. The combination of the car I was driving and the track we raced on recently frustrated me to the point where I just lost my passion for the series.
    I hope you can understand my decision. That said, I’m already looking forward to the next challenge and would love to join you for the upcoming IndyCar events.
    See you all back on the track soon! And as I always say: life is a race.

    The Porsche 935/K3 is not the easiest of cars to get to grips with, even for seasoned simracers, so I can understand how you feel Ertan. TBH the Indycars are not easy either, but I hope you can get connected with them :)

    Thank you for your understanding... You're right, the Indy cars aren't easy, but they have more grip and handling. I get on better with the GT3 / Formula cars than with the old cult cars :)

    They seem to like picking difficult cars here! Though I struggled with the Indycar for tyre feel when it starts to slide, i have found these cars a little easier in that regard around RA, as someone who finds rF2 a bit numb. I also need to stop trying to drive them like a modern car! I just dont like Portland as a track which hasnt helped and picking up the flu for the last few days has prevented me putting more practise in.

    Any setup advise? This track is quite different and i always feel rf2 doesnt always respond to setup changes i would think to do.

    No i dont anticipate doing 60mins, just aiming for 30m!

    I've always felt that too Mark and have had endless conversations with others about that particular issue.
    Something that tames the vicious back-end oversteer traits and brake locking! :D I wish I knew but haven't done any specific setup for this track yet.

    My findings on tuning in to Portland, I'm not an expert in setup tuning.
    • Boost is not you friend here, too many turns, so keep it low, it will also save fuel. When adding boost the car changes dramatic in braking distance.
    • soften the antiswaybars.
    • low 3rd and 4th gear.
    • move the weight a bit to the front.
    • brake early
    Attached a few setups, but mine are only mediocre when comparing skills from your laptimes on Road America.

    I wouldn't complain with your PB of 1.10.706 Thomas :D

    Most problems come from the fact that classic monster cars have too big engine versus what the car can handle. Brakes are not enough, tyres wont hold it and chassis is too weak.
    So you can not push it or it doesnt like you. Key points are knowing where the weight is rolling aka weight transfer and how and when to give some gas to it.
    Once you get there having consistency its very rewarding.
    Setup has to give you comfort and finding more time, can try to manipulate that weighttransfer so can be earlier on gas.

    Locking the brakes...which wheels lock? Move the balance and if still lock, make your life easier and reduce pressure. I got it at 80% and 54 front 46 rear.
    Susnpensions, dampers and arbs are on the softer side of things.

    I think a lot of the issues with braking are down to the different pedals guys use. I've seen setups using 100% pressure and high front bias setting which for me pretty much locks up the fronts with nowhere near full pedal travel, so how those guys brake to avoid that beats me o_O. I was working on brake settings yesterday but have still not found an ideal combination that stays consistent with tyre temps/pressure/wear.

    @Ken Jagger
    I use 100%, but its only because my brake pedal is almost impossible to reach 100% in my wooden diy rig. It's not rigid enough to that force.
    "Normal max" is between 70-90%.

    Q last try was going 1.8.5 but messed up last bit. All so 1st time trying boost and it really caught me by surprise at 1st.
    R was hard. setup was so that had to keep it under certain limits and if cross it, it would upset the car. another factor was my new best friend CrewChief that kept talking and talking and it actually just lifted my pressure all the time. " car behind doing 1.09.2" -- holy shit, " go faster sector 3" --- and so i tried but it went missed braking and to the grass and managed to land car to right side of the track, barely.
    last 10 minutes my brakes just didnt stick anymore but i think it was more of grip from the tyres thus i had some close calls and one piruette in the grass.
    so overall lucky to win it today.

    One week to go until the Porsches return to blow out your eardrums!!!

    2 rounds to go (Road Atlanta and Sebring) and 7 drivers still mathmatically in the running for the championship!!

    If you are new to the series or still racing in it, please make sure that you car choice is up to date. I would like to have no duplicates on track and to have the overlays show all your teams properly. So if you can decide by Saturday 15th March so I can make changes. THANKS!

    See you next Sunday!! :)

    Great event, and thanks for trying out this mod and letting me drive it with your all.

    Seeing how your drive, testing your setups and trying to compete, really has giving me much more information on how this car behaves and how it might should behave.

    It has also made me aware where this car needs some more love, the Barber circuit was where the car felt a bit apart for me, it felt just wrong and strange. Luckily, a logitech update messed up my FFB, so I couldnt participate and make a fool out of my racing. :)

    Now since the event is over, I will pick up developing on this WIP mod. I have already begun testing new tires and some chassis changes, also think I will make more boost clicks in the same range to make it more nuanced. And I think it have some downforce/drag issues, so plenty of areas to look at, but most importantly it still needs to keep it's feisty feel.

    Thanks for it all, maybe I'll join another event later, but for now my mind is on development.

    Thanks very much for wanting to share our series with you Thomas and looking forward to trying out future versions of the mod. If you'd like us to check anything out as you develop it then drop me a message, I'm sure we can find some victims....errr....testers, to help you out with feedback.
