ACC Steering Lock Settings for Every GT3 and GT4 Car

Steering lock is the setting people overthink the most in ACC. The short version: on PC you set it once and never touch it again. On old consoles you set one number per car, and the numbers are in the tables below.

The quick answer

On PC, set your wheel to 900° in its own software and set Steer Lock to 900° in the ACC controls menu. When the two numbers match, the game knows how far your wheel turns and it gives every car its real rotation. You get in a McLaren and the wheel stops at 480°. You get in a Porsche and it stops at 800°. You do nothing.

If you play on PS4 or Xbox One, that automatic step is not there. You pick the value for your car from the tables and set it on the wheel base.

This page is one part of my ACC setup guide. Do this and the force feedback settings first, before you touch a single spring or wing. A setup built on a wheel that lies to you is worthless.

What steering lock really is

Two terms get mixed up all the time.

Steering lock is how far the steering wheel turns from full left to full right. 900° means two and a half turns.

Steering ratio is how much the front tyres turn for a given amount of wheel. A 15:1 ratio means 15° at the wheel gives 1° at the tyres.

A real GT3 car does not have 900° of rotation. Most sit between 480° and 800°. So if your wheel base is set to 900° and the game thinks it is something else, your hands and the hands on screen go out of sync. You turn 90° and the car turns more or less than it should.

That mismatch is the whole problem. Fix it and the car reacts the way the real one would.

How to set it on each platform

On PC the feature is called soft lock. The game stops your wheel at the right angle for the car you loaded. It works with any modern wheel base as long as the rotation in the driver and in the game are the same number. 900° is the safe choice because every car in the game needs 900° or less.

If you run a direct drive base that goes to 1080° or more, the same rule applies. Just make both numbers match.

ACC steering lock for every GT3 car

These are the values per car, taken from the Coach Dave Academy list checked in October 2026. The McLaren 720S GT3 Evo is not in that list, so I have left it out instead of guessing. On PC the game sets it for you anyway.

Look at the spread. The Honda NSX GT3 Evo at 450° and the Porsche at 800° are almost different sports. In the Honda a small input moves the car a lot. In the Porsche you work the wheel much more through a hairpin.

This is one reason a car swap feels so strange for the first twenty laps. It is not only the engine position, which I cover in front, mid and rear engine cars in ACC. Your hands have to learn a new amount of rotation for the same corner.

ACC steering lock for every GT4 car

The GT4 class has the widest range in the game. The Maserati GranTurismo MC uses the full 900°, and the McLaren 570S uses 480°. If you want to know how the two classes compare beyond the steering, read GT3 vs GT4 in ACC.

GT2, single make and TCX cars

The BMW M2 CS Racing at 360° is the outlier. One full turn, lock to lock. The Ferrari 488 Challenge Evo is missing from the source list, so it is not in the table.

For the full roster with classes and packs, see the ACC cars list.

Steering lock or steering ratio: which one do you change?

Leave the lock alone. Change the ratio.

Every car has a steering ratio value in the setup screen, under the mechanical grip tab. A lower number makes the front tyres turn more for the same wheel input, so the car feels sharper. A higher number calms it down.

Here is how I would use it:

• The car feels nervous on turn in and you keep correcting on the straights: go up one or two clicks.
• You run out of hands in hairpins and chicanes: go down one or two clicks.
• You are happy: do not touch it. It makes no lap time by itself.

Changing the ratio does not change grip. It changes how much you have to move your hands to ask for that grip. So pick what lets you be smooth. In a kart you have almost no rotation at all and in a GT car you have a lot, and in both the fast driver is the one who turns the wheel once and holds it.

Mistakes I see all the time

Different numbers in the driver and the game. 1080° in the wheel software and 900° in ACC. Now every car is slightly wrong. Match them.

Setting the car's value on PC. If you put 480° in both places because you drive a McLaren, it works for the McLaren. Then you jump in an Audi and it is wrong. Use 900° and let the game handle it.

Lowering the lock to make the car turn faster. This is the classic one. You are not giving the car more steering. You are breaking the 1:1 match and making every input harder to judge. Use the steering ratio for that.

Turning past what the tyre can use. More steering angle is not more grip. Past a certain point the front tyre just slides across the road, heats up and wears. If you have understeer, more lock is almost never the answer. I go through the real fixes in understeer and oversteer in ACC.

Blaming the lock for a bad field of view. If corners feel faster or tighter than they should, check your FOV in ACC before anything else.

FAQ

What is the best steering lock for ACC?

On PC, 900° in the wheel software and 900° in the game. ACC then applies the correct rotation for each car. There is no faster value. It is about matching, not about pace.

What steering lock do GT3 cars use in ACC?

It depends on the car. The range runs from 450° on the Honda NSX GT3 Evo to 800° on the Porsche 911 GT3 R and the Ferrari 296 GT3. Many cars, like the Mercedes-AMG, Bentley, Aston Martin and Nissan, sit at 640°.

Do I need to change steering lock for every car on PC?

No. As long as the rotation in your wheel driver and in the ACC controls menu are the same number, the game sets the lock per car automatically.

How do I set steering lock in ACC on console?

On PS5 and Xbox Series the game handles it the same way as on PC, according to Coach Dave Academy. On PS4 and Xbox One, set the rotation on the wheel base to the value for your car from the tables above.

Is 900° or 1080° better for ACC?

Neither is better. No car in ACC needs more than 900°, so both work. What matters is that the wheel software and the game show the same number.

What is the difference between steering lock and steering ratio?

Steering lock is how far the wheel in your hands turns. Steering ratio is how much the front tyres turn for that input. Lock is a hardware match. Ratio is a setup choice you can tune to taste.

Does a lower steering lock make me faster in ACC?

No. It makes the steering more sensitive and breaks the match between your wheel and the car. If you want a sharper car, lower the steering ratio in the setup by a click or two instead.
