Monza Sim Racing Guide to Braking Zones and Chicanes

Monza looks like the easiest circuit on any sim racing calendar. Four long straights, a handful of chicanes, and lap times in a GT3 car around 1:47. Then you join your first online race there, and by the end of lap one three cars are in the gravel at the first chicane and your front wing is somewhere near the pit wall. This Monza sim racing guide is about the part of the track that decides everything: braking from very high speed into very slow corners, without losing the exit.

I have driven Monza in GT3, GT4 and open wheel cars across several sims, and the lesson repeats in every one. Lap time here is not found in bravery on the straights. It is found in the last 50 metres of each braking zone and the first 100 metres after each apex.

How the Monza Layout Works

The Autodromo Nazionale di Monza runs 5.793 km with 11 corners. You spend roughly 75 to 80 percent of the lap at full throttle, more than at almost any other circuit. That has two consequences for sim drivers.

• Exit speed is multiplied. A slow exit from a chicane costs time all the way down the next straight, often 0.2 seconds or more.
• Braking is extreme. GT3 cars arrive at Turn 1 at roughly 270 km/h and need to drop to about 80 km/h. That is the biggest single stop of the lap.

Think of Monza as four drag races connected by three chicanes and three proper corners. Your job is to make each connection as clean as possible.

Corner by Corner Through the Monza Sim Racing Guide

Turn 1 and 2, Variante del Rettifilo

The tight right left chicane at the end of the main straight. In a GT3, start braking around the 150 metre board, with full pressure early and a smooth release as you turn in. Hit the right hand kerb lightly and take a shallow line through the left so the car is straight before the exit. Most lost time comes from attacking the second part too hard and running wide onto the exit kerb.

Turn 3, Curva Biassono

The long right hander known as Curva Grande. Flat out in most GT cars. Keep a gentle steering input and position the car to the left on exit, ready for the next braking zone.

Turns 4 and 5, Variante della Roggia

A left right chicane, faster than Turn 1. Brake at around 100 metres. You can use more of the left kerb here than at the Rettifilo, but avoid the sausage kerb on the inside, which unsettles many car models.

Turns 6 and 7, the Lesmos

Two right handers. Lesmo 1 needs a light brake and one downshift; Lesmo 2 is tighter and more important, because it feeds the long run under the bridge to Ascari. Sacrifice entry at Lesmo 2 to get on the throttle early.

Turns 8 to 10, Variante Ascari

A left right left sequence where rhythm matters more than any single apex. Brake once in a straight line, then flow through with minimal steering corrections. Get the first left wrong and the next two follow.

Turn 11, Curva Alboreto

The old Parabolica. Brake late in a straight line, turn in, and then open the steering steadily as you feed in throttle. The exit leads onto the main straight, so be patient. Throttle too early and you run onto the gravel on the outside.

Braking Reference Points That Actually Hold Up

Marker boards are the common reference, but in online races they are often hidden behind other cars. I recommend learning a second reference for each zone: a shadow, a crack in the asphalt, a trackside sign. The broader method in learning a new track layout faster applies well here.

Treat these as starting values. Car, fuel load and tyre temperature can shift them by 10 to 20 metres either way.

Why Low Downforce Is Not Always Faster

The common setup advice for Monza is to strip downforce to the minimum for top speed. On a qualifying lap, that is often right. Over a 40 minute race, I disagree with it as a default.

With wings at their lowest, the car becomes nervous under heavy braking and loose through Ascari and Alboreto. Most drivers lose more time from cautious braking and messy exits than they gain from 3 or 4 km/h at the end of the straight. Try one or two clicks more rear wing than the minimum. If your lap times are steadier and your tyres last longer, keep it. Consistency wins more online races at Monza than outright speed.

Surviving Lap One at the Rettifilo

The first chicane after the start is the most dangerous place on the track. Twenty cars arrive side by side, with cold tyres and brakes, and everyone brakes later than they should.

1. Brake 20 to 30 metres earlier than your normal point on the first lap.
2. Pick a line and keep it. Sudden moves are what cause the pile ups.
3. If you are on the outside, give up the corner. Using the escape road costs less than a collision.
4. Expect a car to miss its braking point. Leave space ahead.

If braking deep into a corner makes you tense, the practice drills in finding the braking point on a corner you fear help a lot.

Using the Slipstream Without Wrecking

Monza rewards the tow more than most tracks. A car following within about half a second gains enough speed to attempt a move into Turn 1, Roggia or Ascari. Commit to the pass before the braking zone, not during it, and never move across under braking. If the move is not done by the board, tuck back in and wait for the next straight.

FAQ

Which car is best for learning Monza?

A GT4 or a road car class is ideal. They are slower, more forgiving under braking and teach you the references without the extreme stopping forces of a GT3 or single seater.

How many laps should practice take?

Plan for 30 to 50 laps before a race. The first 15 learn the braking points; the rest build consistency in traffic like conditions.

Are track limits strict at Monza in sims?

Usually yes, especially at the exits of Lesmo 2, Ascari and Alboreto. Four wheels beyond the white line often gives a warning or a penalty, so build your line inside the limits from the start.

The One Thing to Practise First

Spend your next session on Turn 1 alone. Run ten laps braking at the 150 metre board, then ten at a point you choose, and compare your speed at the exit, not the entry. Once that corner is calm and repeatable, take the same approach to Ascari and Alboreto, and the rest of the lap starts to fall into place. For another classic circuit, the Spa-Francorchamps guide uses the same method.
