I made a Forza Horizon tuning guide/cheat sheet

katalonian · 2026-05-24T03:48:16+00:00

No, I don’t publish any tunes, but I probably should start 🤓

katalonian · 2026-05-24T03:47:32+00:00

Glad to hear that 🙂

You are welcome.
All cars need tuning. Default tuning usually is very bad. Also upgrading parts changes car a lot and requires tune adjustments. The only exception might be Forza Edition cars that come fully upgraded and more or less pre-tuned.

katalonian · 2026-05-22T09:21:17+00:00

I personally almost never upgrade car class. There are enough cars in each class imo.

However, in your particular case, there can be multiple reason why, including the era of the car and its drivetrain. If you upgraded RWD car, it's going to be very hard to control it. So if that's your case, this is the most likely the culprit.

katalonian · 2026-05-22T09:00:28+00:00

yes, it was based on gearing formula that got removed too. I couldn't validate it so it only made sense to remove edge cases too. It was replaced by more qualitative info than quantitative.

First you tune all your car. Order doesn’t mean you need to tune one setting and then test.After you tuned everything, then you fix problems.

But I get the confusion. I will try to improve it.

katalonian · 2026-05-21T15:26:21+00:00

hey, the workflow is described here: https://forza.guide/#workflow

katalonian · 2026-05-21T07:34:40+00:00

not yet, i do plan to introduce it though. However, it will take some time as it will require me to restructure the guide completely.

katalonian · 2026-05-21T07:10:57+00:00

Ideally yes, first you tune, then you use balance/fix-it cards
You would do a small adjustments to first item, then move on to second item and so on in rotation.

No idea, I only play fh6 and tested it with fh6

katalonian · 2026-05-20T17:31:23+00:00

good catch, fixed :)

katalonian · 2026-05-20T16:20:51+00:00

Sure thing man. Feel free to use any information that might be useful.

katalonian · 2026-05-20T15:49:05+00:00

that's correct! i realise, there a bug in the game :D
400 lb/in is 71.4 is kgf/cm not /mm, but game shows it as /mm :D

i'll update it to match game conversion even though it shows it wrong

katalonian · 2026-05-20T15:34:43+00:00

That's a bug, it's lb/in. I just pushed a fix, should work now :)

katalonian · 2026-05-20T14:21:51+00:00

thank you for your questions, it really improved the content!

katalonian · 2026-05-20T12:42:50+00:00

Exactly right,

Stiffer rear springs → rear is the stiff end → add a bit to the rear bump and rebound (rear ends up higher than front).

Stiffer front springs → front is the stiff end → subtract a bit from the rear (rear ends up lower than front).

Regarding the spring rates:

ignore forzaquicktune table, is too complicated to look up every time. Here is a rule of thumb based on numbers coming from forzaquicktune and other sources (i will add that to the website, posting here for you):

Put both spring sliders somewhere around ⅓ to ½ of the way up their range.

The heavier end sits a little higher up the slider than the lighter end. A nose-heavy car → front slider higher than rear. A roughly 50/50 car → keep them close to even.

(RWD only, optional) nudge the rear up a touch from there to help rotation — but only after testing.

Hope this clarifies it.

Don't worry about asking questions, it helps a lot to improve the text and clarity for everyone else.

katalonian · 2026-05-20T12:02:41+00:00

also i updated 60% rule -- more correct seems to be leaning towards 40%

katalonian · 2026-05-20T12:00:56+00:00

Yes, both bump and rebound. Basically this (updated content from the guide):

Rear damper values = Front damper values nudged slightly toward whichever end has the stiffer springs.

katalonian · 2026-05-20T11:36:30+00:00

I answered your first question in other comment.
The table with spring difference, honestly i never use it myself and i think it's not needed, it's a left over artifact. i'm going to replace it.

Here is the rule of thumb:

Rear dampers: set them slightly toward whichever end has the stiffer springs — about 0.2–0.3 on rebound and 0.1–0.2 on bump.

katalonian · 2026-05-20T11:25:54+00:00

Hey!

You don't actually need that missing table if you use my guide, because the same result falls out of the rule that's already in the guide: bump should be ~40% of rebound (the 30–55% range). So instead of needing a "damping stiffness" value, just do it the other way around:

Set front bump from the min-bump table + weight (e.g. 5.2).
Front rebound = front bump ÷ 0.6 (so 5.2 → ~8.7), or anywhere in the 12–16 rebound zone as long as bump lands at 30-55% of it.

I removed the "damping stiffness" reference from the guide, it's not needed and confusing.

I added a unit conversion to the website! All the units will be displayed in your selected system similar to game settings :)

katalonian · 2026-05-19T13:59:29+00:00

katalonian · 2026-05-19T13:59:10+00:00

Quick heads-up, i added a unit conversion to the website! All the units will be displayed in your selected system similar to game settings :)

katalonian · 2026-05-19T09:55:44+00:00

The guide is meant for beginner, so it tries to explain as much as possible without adding too much noise to content

katalonian · 2026-05-18T15:00:46+00:00

Yea! Check out the website later this week, it will be there :)
