https://1drv.ms/u/s!AhFSHJFDC2uXkHwQX95OHZACoZVW?e=W9Qt4W A bit of a setup I was working on in the R8 evo for Kyalami. The rear dampers are set criminally low in this thing which is the reason for that lazy low speed slide during turn in it seems to get. Stiffening them up ( probably at least 7-8 clicks at Kyalami, I went +12) seemed to help it massively on entry. Something to keep in mind for anyone running it in the upcoming season. I don't know how it handles high fuel loads though. https://1drv.ms/u/s!AhFSHJFDC2uXkH2HluJVj9U-W2a_?e=XOIpkD One for the GTR. I think I've found a decent amount of speed in this one. It needs pretty heavy braking to get the thing to rotate. Stiffer front slow dampers help the heavy front end a fair bit. It seems to need stiffer rear slow rebound and softer rear slow bump as well. I don't think I tweaked to much else on it, maybe bumpstop ranges and some ride height changes but i can't remember. Again its only tested on low fuel.
At Monza, the Audi feels very sluggish to turn in. There's not much to play with in the aero balance. I moved the balance a little forwards, but the rear got loose. What do you recommend for better turn in? More rearward brake bias?
I have the same problem with the lexus - I have tried aero and roll bars with similar effects - when I get the turn in I want, somewhere else I get a loose rear. Gonna work on dampers tonight (stiffen rear, maybe soften front, soften front bumps to maybe help with the ascari)
I've tried that, and I think it helped a bit. I'll also try a stiffer roll bar. In other words, trial and error.
Rear roll bar and spring rates can influence the front end as well. You could try going up on the low speed damping all round. Brake bias will help. I dont really understand the default brake bias on the audi. Its basically a porsche in terms or engine placement yet it runs ~64%. I wouldnt even think of going over 60 in it. Running the nsx a while ago it was suffereing on turn in and to fix that i had to use a combination of softer front springs and a stiffer front roll bar. Tyre pressures are also something you can play with. Higher pressures should increase the reactivity a bit, not talking much though +.2 or around that. Higher caster, more - toe at both ends, and lowering the bumpstop range at the front might work as well. Changing the rear toe more towards 0 will help straight line performance a tiny bit too.
Well good poach nice summary I thought. Despite not having much experience specifically in ACC it definitely matched my approach to many other elements in other sims. The dampers thing was a lol! But understand where the author is coming from for a entry level guide. Definitely some value in tuning there if you understand what you're trying to achieve, which is usually more about consistency than outright pace - as they help you better control the transition between grip states. Like say you like your aero balance mid corner but are finding it's introduced lift-off oversteer, or throttle-on understeer, you may be able to correct that with damping adjustments without compromising ultimate mid corner grip qualities.
Good thing about the GTsport and Pcars league is it has default setup, you can rock up and be competitive. Most people don't have the time to tune a setup. I usually don't touch setup as I find it a bit daunting. At least with that video it gives a good starting point and doesn't take long to do. Gives a good lap time yield. The link at the start of this thread gives a good explanation of the suspension settings. That will take more time to do and sounds like you need a really good understanding of what your car is doing. I will be stealing that link too!
Fixed setup is definitely a good formula, until you have dynamic track conditions and an interdependent tyre model P.S. I liked the reminder about brake ducts influencing tyre temperature (not just brake temps) - I often forget that part
