Stable Porsche 992 GT3 R Setup for ZOLDER - Assetto Corsa Competizione.

Note: Negative toe might still work in the qualifying environment. But all my setups will for now utilize positive or only slightly negative toe as I expect it to be the more sustainable solution.

The Porsche just feels great with a balanced race setup. Ever so slightly willing to rotate on entry, stable in the middle off throttle and again willing to just mildly rotate on exit (apart from high speed, where its pushing a bit). It might be best simulation ACC has to offer. Everything feels really round and smooth, no excessive behavior in any situation.

Overall the new Porsche needs less steering as before and it's easy to turn too much. The high steer ratio helps to be precise.
Be careful on turn in. The tires likely need half a turn or more to build temperature on the surface and they are more snappy on entry when still cold. You can get them warm more equally by reducing camber and going for more positive toe. This will cost lap time in general, but might gain you time if the car is unrealiable on corner entries for you. While the car keeps the crazy rotation off throttle, the center of that rotation seems far more in the center of the car now, than around the tip of the nose, which makes it rotate more like a mid engine car. The rear doesn't feel quite as exposed on corner entry, and you get actually turn into the direction you want to go, instead of controlling a permanent slide. In Q the weight balance is still very far to the rear, hard to do anything about it. I tamed it as much as I could and again no negative toe needed here for (most of the) lap time.

Zolder
Of course a lot around Zolder resolves around the chicane and how good you can take the kerbs. The issue is: The Porsche just doesn't and I tried various approach which all failed. So when the chicane can't be solved, we shouldn't compromise the car for it. You will need to solve the chicane driving wise, that IMO means to not take the first kerb at all and only attack the right side kerb with the right tires only. Ideally, you leave both kerbs aside. This in turn gives us a good car anywhere else. Turn 1-4 are really balanced. You can ever so slightly kick the rear out on entry and keep a nice and steady rotation through them. All turns are tightening here on the exit. and thus they all want throttle before the apex, but with a lot of the rotation done halfway through the turn already, which means we want late entries and apexes. The 2nd chicane is all about finding the track limits and keeping the car stable. The throttle pedal is a key device here to control the cars ride height, load distribution and differential. Once you get the hang of that, you'll feel much more comfortable. The brakes are very tricky here in Qualifying. So don't be too harsh, as the front losing and regaining grip can destablize the entire car.

Driving

  • Aim for late apexes and dont shy away from a short shift or staying in the higher gear option in the first place in the lesmo's or ascari for example
  • your brake is more than a means of deceleration, it also controls pitch and especially in Q this will be key to managing rotation on corner entry - most pronounced going through sector 1 and the medium speed corners there. It generally needs careful trailing to not lock the front tires, but also to keep the car rotating
  • on throttle the car will keep rotating, dont just floor it as that might exaggerate it - take a close look at my throttle traces. TC2 in Q seems fine, but you want TC1 on the exits of every corner if you can handle it. TC3-4 for more stability and predictability at almost no time loss in the race (apart from the hairpins really). For the race start with TC3 and you'll like go up to 4 once the rear tires start to drop. TC2 also seems stable enough for advanced drivers.
  • dont steer too much, progress into it
  • In lap comparison focus on where the car is slow, where its tight and where its wide. Replicate that first and foremost, the other inputs will come automatically with that.

Adjustments

  • If too oversteery: Stiffer front spring (this will lead to more oversteer later in the stint, try the other options first), stiffer front roll bar, less rear ride height. One click at a time. Other options are to use less front bump stop range if particularly the braking into fast corners proves tricky. if you have issues on exit, increase rear bump stop range.
  • The brake bias is tricky. If it's too far forward the front will suddenly regain grip and the rear snaps. If too far back the rears might lock. Higher ABS here if you cannot handle it, but likely at a time loss. Clean trailing will pay off.
  • higher preload can give more turn in stability, but will come with more nervous exits
  • lowering front and adding rear camber might further stabilize the car (in race)
  • lowering the caster also gives more predictability
  • Some drivers might like a car with less rake for better drivability. It does not seem to be too problematic to lower the wing in turn for 2-3mm lower rear ride height.
  • rear tire wear remains an issue. Lower camber all around the car might help paired with more positive rear toe - but its just something you can't fully control. Adding more understeer with higher ARB or a lower rear ride height will be more impactful

Tire pressures
Aim for just shy of 27 psi for solid support from the tire without surprises. You can play with the fronts at lower pressures, so they develop some temperature. Yet we have a lot of high load corners here and a stiff tire feels much more communicative than a soft one. Also i deliberately chose higher rear pressures to keep the temps ever so slightly lower. 

Lap times
Q fuel: 12L (This is safe to use for the sprint races adding the necessary fuel of 40L - maybe add 1 click of rear ride height)
R: 100L (including formation lap)

Race
You need to test how you use the tires. For me this would work for a stint, as I can keep the wear similar (but by far not the same) on front and rear tires. If you use the rears more you will need to add more understeer to the setup with the tips above to keep reasonable balance throughout the stint! Generally you will benefit here in the longrun if you don't push too hard in the beginning, make sure to not overcook the tires in the last sector's right handers. Rather wait a tad longer before adding power and do so progressively to not force the rear into a slide. Into the corners make sure the car is stable with a tad understeer to utilize the fronts instead of overusing the rears.

LFM: For the shorter LFM races you'll likely be best advised with the Q set and a bit of fuel, less front pressures, but without any other changes - if anything increase rear ride height by a click.

Is an updated setup for the current version in the pipeline? Would've appreciated a notice when buying the bundle that some setups are for very old versions.
