These are the settings I would start from in Assetto Corsa Competizione with a Thrustmaster wheel. You set two places: the Thrustmaster control panel on the PC and the force feedback block in the game. The table below has both for every model.

I checked the values again on 5 October 2026 against the baselines that are published today. The old version of this page had 333 Hz, no minimum force on belt wheels and a brake gamma of 2.00 on the T300. All three were wrong and I have changed them.

Step 1: Thrustmaster control panel

On PC, open the Thrustmaster control panel with the wheel plugged in. First check that the firmware is up to date, then set this:

SettingValue
RotationThe full rotation of your wheel, see the table above
Overall strength of all forcesSee the table above
Constant100%
Periodic100%
Spring100%
Damper100%
BOOSTOff

Rotation by model:

WheelTypeRotation
T128Hybrid belt and gear900
T150 / TMXHybrid belt and gear1080 (T150), 900 (TMX)
T248Hybrid belt and gear900
T300 / TXBelt1080 (T300), 900 (TX)
TS-PC / TS-XW / T-GT IIBelt1080
T818Direct drive1080

Leave constant, periodic, spring and damper at 100%. They are ceilings for the kinds of force the game can send. If you lower one you cut a part of the signal and the car feels different in ways that are hard to trace back. The only slider you use to change the strength is the overall one.

BOOST off. It makes the wheel stronger in a way that is not linear, and you want twice the force from the tyres to feel like twice the force in your hands.

On PlayStation and Xbox there is no control panel. The wheel runs at its full rotation and full strength, so you go straight to step 2. On the T248 you can also change the force feedback mode on the screen of the wheel: use FFB 1, the linear one.

Step 2: ACC wheel settings

In the game go to Options, then Controls. Pick the wheel on the left and load the Thrustmaster preset so the buttons are mapped. The force feedback block is on the same screen. Put in the row of your wheel from the first table.

Why the numbers look like this.

Gain 95 to 100% on belt wheels. A T300 gives you a bit under 4 Nm and a T248 about 3.5 Nm. That is not much, so you ask the game for nearly all of it. The T818 is a 10 Nm direct drive base and has force to spare, so the gain goes down to 65% to keep the signal from clipping.

Minimum force 4 to 7%. A belt has a small dead zone around the centre, smaller than the gears of a Logitech but it is there. Minimum force lifts the light forces above it. The old page had 0% for most models, and with 0% the first degrees of steering feel empty. The T818 has no belt and stays at 0%.

Dynamic damping. This is the value where published baselines agree the least. For a T300 I found 30% and 40% from two sources I trust, and I would start at 40%. Stronger bases can run more, because they have the force to spend on it. If the steering feels heavy and slow, take 10% off. If the wheel moves around too much on the straights, add 10%.

Road effects 0 to 10%. It is an added effect, not information from the tyres. A belt already smooths the signal a bit, so a little can help on a T248. Start low.

Frequency 400 Hz. The highest value in the list.

Why the overall strength is not at 100%

A belt driven wheel gets warm when it works hard, and when it gets warm the force drops. You feel it in a long race: the wheel is strong for the first laps and lighter after half an hour.

That is a problem for your driving, because your hands learn one level of force and then it changes. Running the overall strength at 65 to 80% keeps the motor cooler and the force stays the same from the first lap to the last. I would always take a slightly lighter wheel that is the same every lap.

The T150 and the TMX are the exception. They are weak enough that you need everything they have.

How to adjust from here

Change one value at a time and do five laps before you judge it.

ProblemChange
Dead feeling around the centreMinimum force up 2%
The wheel shakes on the straightsMinimum force down 2%, then dynamic damping up 10%
The steering feels heavy and slowDynamic damping down 10 to 20%
The force goes flat in long fast cornersGain down 5%
The wheel gets lighter during a long raceOverall strength down 10% in the control panel
The kerbs are too loudRoad effects to 0%

The row about fast corners is clipping. Switch on the FF bar in the HUD and watch it in the fastest corners. A flash at the top over a kerb is fine. If it sits at the top through a whole corner, lower the gain. My ACC HUD guide shows where the bar is.

Steering lock

The rotation in the control panel and the steer lock in the game must be the same number: 900 on a TX, a TMX, a T128 or a T248, and 1080 on a T300, a T150, the TS bases and the T818. When they match, ACC gives every car its real steering lock by itself and you never change it again. The lock of each GT3 and GT4 is in my ACC steering lock guide.

Brake gamma

Start at 1.00, which is linear. Most Thrustmaster sets come with pedals that measure travel, not pressure, so it is hard to be precise near the top of the pedal. If you cannot reach 100% without standing on it, raise the gamma in small steps, once, and then leave it alone. Your foot needs the same pedal every day to learn it.

In a GT3 car most of the lap time is in the braking zone. My guide to braking technique in ACC goes through it.

T598 and other new bases

I do not have a checked baseline for the T598 yet, so I will not give you numbers I cannot stand behind. The logic is the same as for the T818: it is a direct drive base, so minimum force 0%, frequency 400 Hz, and the gain as high as it goes without the FF bar sitting at the top in fast corners. My T598 review covers the base itself.

The general logic of the force feedback menu, with the values for other brands, is in my ACC FFB settings guide. There are separate pages for Logitech and Fanatec wheels. If you are choosing a Thrustmaster base, the Thrustmaster wheel base lineup guide compares them, and I have reviews of the T300 RS, the T248 and the T818.

FAQ

What are the best ACC settings for the Thrustmaster T300?

Overall strength 75% in the control panel with rotation at 1080. In the game: gain 95%, minimum force 5%, dynamic damping 40%, road effects 0%, frequency 400 Hz and steer lock 1080.

What are the best ACC settings for the Thrustmaster T248?

Overall strength 65% and rotation 900 in the control panel, FFB mode 1 on the wheel. In the game: gain 95%, minimum force 4%, dynamic damping 65%, road effects 10% and frequency 400 Hz.

Are the TX and the T300 settings the same?

Yes, apart from the rotation. The TX turns 900 degrees and the T300 turns 1080, so the steer lock in the game follows that number.

What are the best ACC settings for the Thrustmaster T818?

Master gain 100% on the base. In the game: gain 65%, minimum force 0%, dynamic damping 100%, road effects 0% and frequency 400 Hz. Lower the gain if the FF bar stays at the top in fast corners.

Why does my Thrustmaster wheel get lighter during a race?

The motor and the belt get hot and the force fades. Lower the overall strength in the control panel by 10% and make sure the vents of the base are not covered.

Should BOOST be on or off in ACC?

Off. It adds force in a way that is not linear, and you lose the link between what the tyres do and what you feel.

Do these settings work on PS5 and Xbox?

Yes for the values in the game. On console there is no control panel, so the wheel runs at full strength and you adjust with the gain.
