Forza 7 Tuning Guide

Part 1 - Forza Tuning Basics

Understanding Car Types and Body Types

When it comes to tuning in Forza the most important aspect you need to understand is the concept of car types and body types.

Car types provide a general classification of all cars in Forza and group several body types. Each car type needs a distinctive way to be setup in terms of tuning.


The following car types exist in Forza:

  • Production Car(street cars, muscle cars, compact cars, sports cars, rally cars, SUVs, utility cars, off-road cars)

  • High Performance Cars (super cars, hyper cars)

  • Race Cars (GT race cars, touring cars, NASACAR, V8 Supercars, race trucks)

  • Prototype Race Cars (LMP cars)

  • Open Wheel Cars (open wheel sports cars, open wheel off-road sports cars)

  • Open Wheel Race Cars (F1, IndyCar, Formula-E, classic GP cars, Formula Mazda, Formula Ford)

Now what is a body type? A body type defines the basic characteristics of a car such as suspension geometry and chassis and suspension stiffness. Forza does not simulate cars on an individual car level but on body type level. That means all cars that share the same body type are running on the same virtual representation of the car.

An example would be a classic American muscle car that  features a very conservative suspension geometry combined with a soft chassis and suspension setup that gives you that unique "boat like" handling on roads.


In contrast modern F1 race cars features a unique open-wheel suspension geometry along with a much stiffer chassis and suspension characteristics that is suitable for high-speed racing on ultra-flat race tracks.

Body types are similar to the concept of divisions that group similar cars to achieve more close racing but they are not identical. Sometimes divisions contain cars of different body types or cars of a certain body type are spread across several divisions. Think of divisions more of an organizational grouping of cars whereas body types define the physical (or simulated) taxonomy of all cars in Forza.

To further diversify body types with regard to the period of time a car has been built Forza uses an era system:

  • Modern: cars built 1995 or later

  • Early Modern: cars built 1981-1994

  • Vintage: cars built 1960-1980

  • Early Vintage: cars built 1940-1959

  • Pre-War: cars built before 1940

That means the correct body type of a 1979 Chevrolet Camaro is a "Vintage Muscle Car" whereas a 1987 Pontiac Firebird TransAm is an "Early Modern Muscle Car". 

Now how do car types and body types affect tuning? Generally speaking older cars require a stiffer chassis and suspension tuning and a more conservative alignment and differential tuning than modern cars and race cars require softer chassis and suspension tuning and a more aggressive alignment and differential tuning than production cars.

Open Wheel race cars and Prototype race cars however don't follow this pattern because they are exposed to extreme forces while cornering so they need very stiff chassis and damping setup to handle those forces.

The following table gives an overview how era and car type affect the different tuning areas

Understanding Tuning Relevant Car Properties

While car type and more specifically body type are the most important factors when it comes to tuning they are also other individual car properties that have great impact on the tuning, most notable are weight, power and drivetrain.

The following table gives an overview which car property affects which tuning area. Please refer to the related section in the tuning guide for detailed explanations.

only in special cases

As you may noticed brake tuning is the only area that is completely car independent. All other tuning areas are more or less dependent on the car you are using.

So these are the basic Forza tuning principles. With the basics being laid out we are now ready to dive into general tuning.
