    Do you have any solutions/hints/suggestion how to achieve a safe/understeery setup in GT3 gen2 cars, especially the porsche 992 gt3r?

    I tried (I think) everything, stiffening the front (both springs and arb) while softening the rear, increasing rear camber, etc.

    But I always have a "more or less" oversteery setup.

    I'd like to know if in your opinion with such car is achievable a push-understeer driving feeling, where the car pushes wide on throttle out of corners.

    try reducing the number of clutches and rising preload (I'm not a pro at setups, but usually I start with changing the diff as I read somewhere on the internets)

    Hi,

    Maybe try less clutches on rear dif and higher preload?

    Hi,
    Wow same advice given at the exact same time!

    I don’t think you can with that car. I was testing this actually not too long ago with some extremes setup changes, but it didn’t really ever end up to be like that (felt quite safe to me though). Stiffened up the front, made the weight transfer to rear on throttle to be as dramatic as possible etc, but it wasn’t ever exactly that understeery on exit/on throttle.

    of course you can balance oversteer with diff changes (those changes I did worked for that too), but basically it usually just makes you slower.

    Thank god for the Internets :D

    to be honest , Imo the default set up for the porsche is pretty good .
    any tweaks i’ve tried have made it slower .
    Outside of moving BB a couple of clicks forward to improve stability on entry and reducing TC to 2-3 to smooth out exit on initial throttle. you really just need to embrace its fundamentals of willing rotation mid corner and traction on exit .
    slow in fast out , and maintenance throttle on entry, but a little extra preload can help too.

    Yea, I agree, you have to embrace its characteristics and use them, they can be an advantage. The Porsche is just very different due to the engine being at the back. I think if you like more understeery handling front-engine might be the way to go then.

    • -2.0 camber front
    • -3.0 camber rear
    • toe to -0.6 or even lower at front
    • toe rear near to 0 (might even go to -0.2 if the car allows for it)
    • reduce disk at rear to 4
    • increase preload to >315
    • wings to about 7-8 (remove any front wing)
    • rake of about 10-13mm front to rear
    • maximise front suspension and front (slow) dampers
    • increase front bumstop to minimize dive until you see about .3-.4 suspension movement (or max if the car does not allow that).
    • get both anti roll bars at about 2/3 of max, maybe 2-3 clicks lower for rear
    • increase engine braking to 5.
    You may want to apply all of that or only part of it, this should definitely make cars less snappy.

    Disclaimer, it worked for me (even some adjustements would tend to feel innappropriate at first) your experience may vary.

    Just wanted to say thanks a bunch for sharing this setup! Worked very well for me, really gave me the confidence to push. Knocked a good 2-3 seconds off my previous PB at Bathurst... managed to get down into the mid-2:07's (I know, that's way off the pace but it's fast for me, so thank you!)

    You're welcome, now it is a matter of getting used to the track. Once you feel more confident you can try getting any of those setup values more toward a "snappier" feeling to make sure you drive at the limit. Also make sure you avoid to bottom out (scratching noise from your underfloor), this is the first thing to resolve in this game as it would cause major loss of speed (or rather lack of speed gain) and huge risk for stability. I see lots of people forcing themselves to run as low as the game allows it and using low wings and wondering why I overtake them in straight with higher wing setups, the answer is always ride height and bottoming out. This might be something to look into for your butthurt practice. If you bottom out a lot in the straights and cannot stiffen the car further just raise the overall platform by 3-4mm.

    I know this was a typo, but bwahahaha!!! (Actually it's appropriate, since that's usually how I feel after I've raced there :D )

    Re: bottoming out and ride height: is there a way to check telemetry of the car, e.g. ride height, spring compression, camber, etc. either in real-time or while watching a replay? I'm guessing I'd need to look into setting up some sort of overlay with Simhub or something? That's one of the few things I like about Forza Motorsport, that it gives you easy access to monitor all sorts of stuff like that.

    Well you have different HUD you can cycle through including some basic in-game telemetry. You can also setup a motec extract (you should be able to find how to set that up digging in the forum). Just be mindful of how far you really want to push this game engine, the motec extract for example will be sampled at 60hz max, which is really too low to get meaningful data for your dampers.

    Huh. Now that you mention that, I remember seeing a tooltip on a loading screen, mentioning some kind of FFB widget in the HUD, but I couldn't figure out where to access it. Guess I'll have to do some digging and see if I can find something useful. Thanks for the heads up.
