PPiDrive,
dude, you’ve already helped me so much! I’ve been reading a TON like “creeper status” of posts from both you and Spot the Kitty and it’s been helping me out ALOT.
I’m humbled that it seems you enjoyed my tune. It’s not great, yet. Believe it or not, I still feel like I can get a bit more out of her. I use only my controller, so there’s only so much there, but it is what it is. I’ve been playing Forza since the beginning, it’s just the “Cudafish1966” profile is “newer.” Basically was playing on other friend’s xbox’s while I had PS1 and PS2 with Gran Turismo. You could say I was “converted” back in 2010, and I haven’t looked back. Horizon is amazing to me. ultimate fantasy.
beyond that, something I think others may not realize -
in real life, we don’t have “telemetry” especially “grassroots” racers like myself. I haven’t driven hardcore in about 7 years, but I once had my pro license in SCCA and NASA. I had the (for the time) wicked high-tech laser thermometer (actually “borrowed” it from work, I was a chef) to check tire temperatures. But anyways, in real life, all we have to go off of is “feel” and lap times and section times and speeds. I think the “telemetry” in the games is great! Wish I had it in real life, and I see it as a bridge to help connect us better to the cars, but it isn’t required.
My Zagato is based solely on feels, miles, and time. I try to find the speed traps, both the averages and top speed ones, and blast through them to see how the car does. Then I use courses like the ones in Sisteron to get my lap-times and feeling of the turn-ins, oversteer-vs-understeer initials, oversteer-vs-understeer exits, and speeds as best I can.
Basically, the Zagato started out “life” in my “generic heavy Front Engine/Rear Wheel Drive” settings. I’ve been using these between Gran Turismo and Forza for God, I don’t want to admit it, but about 16 years or so. Ever since I started spanking the AI in GT2 back on PS2 with my 69 Camaro z/28.
It’s been changed of course through the years, but it’s basically this in Forza:
Alignment -
Camber - Maxxed out
Caster - Maxxed out
- → these two have changed drastically since FH2. Back in Forza 2, 3, and 4 it was always about 2.5 neg front camber, 1.5 neg rear, and 5.5 caster.
Toe - Zeroed Out
Tires -
Fronts - 29psi
Rears - 28psi
Gearing -
get the real race-cars gearing if you can, adjust from there
Aero -
this I put all the way down to start. I don’t want to depend on Aero. I’d rather have it as a “secret weapon” just like in real cars for when the time comes. Tight tracks, I tighten it up, loose/fast tracks I lighten the load… always knowing the car was tuned for practically ZERO Aero to begin with. AKA, my Zagato drives fine without the rear wing 
Brakes -
60% forward
125% force
NO ABS
Suspension -
this gets “hinky”
basically I start with even sway bars, even springs, and maxxed out rebound, and zero bump.
I then adjust from there based on how the car drives. I always try to leave the sway bars alone. In the real world, they’re one of the things you can’t really mess with… easily. Whereas coilovers, shocks, etc, hell even alignments are easier to tune at the track than most sway bars grassroots guys have on their cars. Nothing like binding up 10minutes before “GO.” So we don’t mess with them.
beyond that PPiDrive - I have a Vanquish too. I’ll directly put in my inputs for the Zagato into the Vanquish. I’m expecting her to be looser. She’s not as rigid of a car, and quite a bit heavier. But I’ll see what I can come up with.
Right now, honestly this made my day. I was getting frustrated at my Zagato and losing faith. I usually can get into the 1% range on the leaderboards in Rivals. And I usually don’t try to go past that. I figure being in the “Top 1%” - thinking back to “TOP GUN” - is good enough. But man, the lap times at Castello’s High Speed Circuit just completely deflated me.
basically beyond these Aston’s. My next goal is going to be MY old GT, the Cobra, and the Daytona…
to put it plainly, I have real world experience with replicas of those cars, and I was wicked excited to see in the bucketlists the Cobra and the GT actually behaved much better and more as they should in this game than in FH1.
