"Every Racer's Guide to Suspension Tuning"
Recommended for every one interested in handling, especially for racing and high performance

A Series of Articles on Race Car Chassis & Supension Set Up. (All of the following is superceded)
|Grip? Balance? Transient
("transient behaviour" might also be considered as "handling balance variation")
These are the big three questions we will attempt to unravel in this series of articles.
Race Drivers: Learn about the responses of your race car - what you are doing to it, and what it is doing to you - so you can focus your efforts in areas bringing greatest improvement. If you were a young driver, testing for a V8 SuperCar drive, this is the stuff you would be expected to know. You should be able to work with the team to balance the car.
Race Engineers/Mechanics and Drivers Responsible for
their Own Set-Up:
It is generally accepted that feedback from the driver is the most important input for tuning the race car balance - the driver can feel very small changes in balance. However, the driver will not be as sensitive to small changes in overall grip. Therefore, improvements in overall grip may come from any of a multitude of analyses and or data sources.

anything we can do to make our Driver/Race Car combination faster, through chassis
and suspension development. The techniques and ideas we can use apply in all forms of racing - circuit, speedway, offroad and rallying, even though the requirements of car performance will be different.
you are building a street car, or performance road car, you will also be interested in
For our purposes in this series of
articles, we will equate "handling", with the "chassis and suspension
Consider the following list of chassis set up items that could influence handling:-
Tyres - tyre and wheel width,
construction, compound, temperatures, pressures
This is by no means a complete list, and
does no justice to the relative importance of the various
Of all the theory that might be implicit
in the above list, the most important for the Race Driver
You won't read stuff exactly like this anywhere else. I draw heavily on the work of Mark Oritz, writing in "Race Car Engineering" magazine. From my own experience as a driver (many years ago), and suspension tuner, I have attempted to generalise his work, and make it more usefull for track tuning.
