Assetto Corsa Competizione: Monza setup Porsche 911 GT3 R

Assetto Corsa Competizione setups are difficult things to master.

With far more intense options and engineering lingo than games like F1 2020 or Gran Turismo Sport that many players start on, it can be a daunting task to make an ACC setup that works.

That’s why we are here to help you out!

ACC setups

There are a few basic rules to follow when it comes to. The first is tyre pressures.

Ideal PSI for dry tyres sits around 27.5. Your PSI will fluctuate with tyre temps, but when they are that wonderful green colour you want them in a 27.3-27.9 PSI window.

Next is baselines. The default setup is a nice start, if slow, but the preset “aggressive” setup is a good starting point to begin tinkering from and correcting to your driving style.

DANGEROUS DELIGHT: The rear-engined Porsche can be a handful in mid-high speed corners

The aggressive setup can be prone to snap oversteer, something that is only amplified in the rear-engined Porsche 911 GT3 R.

However, it will do things like lower your TC/ABS and give you a better ride height.

A good setup will give you that last second or so of performance, so let's see what we can do around Monza in the 911...


The first page of your setup is perhaps the most crucial of the lot.

CONTACT PATCH: Getting your interaction with the track right is key to a good setup

These PSI values mean that when hot the tyres will be in the optimum operating window.

If you are doing a very long race, 2 hours or more, you will want to take the PSI down a touch.

Track temperature will also create some fluctuation in your PSI so if you're racing at night bump it up! We've also eased back on the rear camber to keep your tyres alive for a little longer.


Electronics is all about traction control, ABS, and the ECU mapping.

PUT THE POWER DOWN: If you are confident on exit you can drop more TC

It's a very individual part of the setup and one that can be changed mid-race so you don't need to spend too long on it.

In enduro races you can click everything up to save tyres and fuel.

Fuel & strategy

Again, this is very session dependant. Most people do 20 minute races that don't require a pit stop. However, if you are stopping make sure you set your new tyre PSI correctly!

PICK YOUR BRAKES: Each set of discs is slightly different

The key here is picking your brake set. The shorter the race you are doing, the lower the value of brake disc you want.

However, the very last set is for practice only as it replicates very worn brakes so you can get a feel for late stint racing and should not be used for an actual race!

Mechanical grip

The suspension settings are crucial in ACC.

BALANCE IS KEY: You can create a lot of problems by making the front very different from the rear

While Monza may just be three straights and three chicanes, it also has some vicious kerbs and very heavy braking zones.

The Porsche is also very prone to oversteer, so if you don't like that you'll want to stiffen up the rear, or loosen the front, to correct with setup rather than driving style.

Just beware on turn-in at Parabolica!


Dampers are very hard to get a feel for in ACC unless you have the highest of high-end sims.

WHAT DO YOU DO HERE: It's hard to feel the changes you make here

Generally softer is better, and is especially helpful if you get too greedy with kerbs. However, making any dramatic change will have the car pitching around more.


This is vital for Monza. You want as little aero as possible.

CAN WE TAKE THE WING OFF?: Drop everything to 0!

You want no wing so you can fly down the straights, however if you are struggling to keep the rear under control you can add a click of wing to help.

Likewise, If you feel you are loosing the rear off-throttle then you can drop the rear ride height a few clicks to help. It will create more understeer and stability.
