Hi!
I’m pretty confident when it comes to tuning AWD cars, but RWDs are still problematic.
Do you have any tips / personal preferations regarding ARBs, tire pressure and diff settings for RWD cars?
From what I have heard and concluded you would generally prefer:
-Stiffer front, softer rear regarding springs
-ARBs F ~35 R~25
-Tire pressure - F slightly higher than R
-Diff Acc ~50-60%, Dec ~20(?)%
Please tell me if my conclusions are somewhat correct and zirca universal for RWDs in A-class.
For Differential try 35/10 or 55/15 for lower hp cars. The higher the acceleration more aggressive the car will feel and you gotta throttle control more often when exiting corners.
ARBs i ussually go 15/55 or 25/55 or extreme 1/65 just try and see what results.
Any strong tuners here? Can someone explain one thing to me like I’m a total noob?
For the second Forza in a row, I keep feeling like it’s basically impossible to build a competitive S1 car while keeping the stock engine and RWD setup. Take the GR GT for example. It looks like such an obvious “meta” car, but no matter how hard I try to tune it while keeping the original drivetrain and engine, I still get smoked online by people running the usual AWD + engine swap builds. And this car is far from the only example.
I really want to believe I’m just a bad builder who can’t fully optimize a car, but in practice it always feels like “meta engine swap + AWD = free win.”
But what’s even the point of picking a car if the only thing left from the original is the body shell? Am I really the only one trying to keep cars at least somewhat authentic?
Would genuinely appreciate an answer from someone who actually knows tuning 
If a different car/build/tune could beat the meta, it would then become the (new) meta.
It can’t be helped. It’s always been like this, & likely always will be: what we enjoy driving more & what wins more are often not the same car/build/tune.
It’s inevitable with the freedom of having so many options to configure cars in so many ways.
The only way to win without using the meta is to compete with players whose skill level is so much lower than yours that they can’t even win when they’re using the meta versus your non-meta - but that’s not very satisfying either… like winning a boxing match blindfolded against an infant who’s not blindfolded.
I know the “purist” approach has its appeal, but I try to remember that they’re not real cars - they’re just interactive pictures of cars in a video game.
They’re not real engine swaps, or real drivetrain swaps, etc. - they’re just options to select from an on-screen menu that can make the virtual car complete a virtual race in a quicker time.
These are not real physics - it’s just this software’s imperfect approximation.
Etc.
Nobody’s gonna care.
You’re not “ruining” a real car.
This is an entirely self-imposed restriction.
There’s nothing wrong with trying to keep a car as authentic as we can if that’s how we like it, but it usually comes with a compromise on the car’s competitiveness in a video game.
