Making Progress

A guide to GT4 suspension & brake tuning

Introducción

Welcome to what I hope is an informative and useful guide to suspension and brake tuning with Gran Turismo 4.

This guide started life as I began typing out and clearing up my own notes on tuning; it has gained a life of its own and I wanted to share what I had put together with others.

What you are now reading is basically the product of the last 9 months of my life with GT4, combined with my years of work in the motor industry and driving.

The notes and techniques for tuning contained within this guide The are not 100% real life, but rather the effects I have found from tuning in GT4. While a large amount of this does meetwith real world practice, it is not a guide to tuning real cars and should not be taken as such.

In addition to the tuning guide for suspension and brakes, you will also find information relating to tyre selection andthe fitting of racing brakes. While not strictly speaking tuning information I have included these sections as I have found them to be extremely useful when tuning.

I have obviously not covered every tuning option inGT4 in this guide and I hope to find the time to write future guides on the areas I have not covered here.

In closing I hope that you, the reader, find this guide as useful and enjoyable as I found writing it to be.

Regards

Scaff

REAL VS GT4

Tuning in GT4 is not the same as tuning in the real world, a number of distinct differences can be seen between what is real and what is simulated in GT4.

The principal distinction is in how real world tuning practices relate to GT4 tuning practices; while the general approach and theory of real world tuning can be applied to GT4 with similar results, they are not exactly the same.

The changes made in GT4 tuning do not have the same level of effect that they would in the real world, so for example if the rear springs of a car are stiffened they will increase the tendency to oversteer, both in GT4 and the real world. However the GT4 car would not be subject to the same level of oversteer as the real car.

As a result while real world practice and theory can be applied in GT4, exact real world values can not be used.

One important aspect of real world settings that is carried over to GT4 is that every set-up is individual to the driver; even in the same car, set up for a single track, settings that work for one driver will not be ideal for another driver. Sometimes only minor changes will be needed; in other cases the settings may
