Hey, I realize this thread is mega old. Back during the release time as a kid, I would come here to get your setups.
Now I am again, I'm playing it again on RPCS3 and honestly as long as you do all the instructions to remove the bugs it's just a much better experience on a modern controller. I've been playing with my dual sense, and binded X to R2 and Square to L2 and it gives you linear input for both throttle and brake, meaning you have better control of the car (obviously). Downside is the pitstops, but you get used to it eventually... And adds to the challenge I suppose since you'll have to make up for the initial bad stops with your driving.
Also I have my PS5 controller "overclocked" to 8000KHz polling rate, so it's another element that helps since the game is 30fps. Those minor input delay benefits help a lot for this face paced game. (Also I possibly have a friend working on a 60fps, if not dynamic frame rate, we'll see).
What I found is with the linear changes, I can use much more rearward bias and trail brake, it is quite literally a second if not seconds at some circuits.
So I've been using your setups and basically changed my brake bias to:
P1: 55/45 (main)
P2: 60/40 (secondary for if the rear gets loose under braking in some corner)
P3: 65/35 (for if it rains, or you're really struggling with rear stability)
The trail braking also allows me to run more front wing and get a more oversteery setup, hence adding to the why it's so much faster.
Also in general I found bottoming the car made it much better, especially if you're not running over kerbs. Even Monza I could run 10 ride height, and just stiffened the suspension by 2 clicks from where you had it. Aids corner speed so much. I also tended to run more aero than you in general, 10 more on front and 5 more on rear. I.e if you had 60/65 then I'd do 70/70, or 60/60 into 65/60.
Hope you're still active on here to see that someone is appreciating your work 14-16 years later
