Accounting for Tyres So far in the process we have ignored the effects of tyres for calculating our spring rates. One aspect of the tyre to consider is the grip generated due to the normal force being applied through the tyre. This is the grip …
We spend a lot of time writing about suspension and different tips and tricks to achieving a great set up to make you and your car as fast as possible around the track. However, a suspension set up can often only be as good as the tyres used. This is because the aim of a perfect set up is to deliver excellent dynamic feedback to the driver as well as getting the most out of the tyre in order to generate the highest amount of grip as possible.
Anti-squat, anti-dive and anti-lift geometry which will be referred to as “anti-geometry” when discussing them as a whole is a form of geometry at the front and rear wheels that alters and controls the amount that a car will compress the springs due to acceleration, deceleration or braking conditions.
Wheel Rate Wheel rate is effectively the spring rate when measured at the wheel as opposed to at the spring. It is important to understand the wheel rate of a vehicle for calculating the spring rates and understanding the car dynamically. Coil Spring Wheel Rate …
What is an Installation Ratio? An installation ratio is the ratio between how much the spring and damper moves in relation to how far the wheel and tyre move. In general, the wheel and tyre will move a further distance than the spring and damper. …
What Is Slip Angle? A slip angle is the difference between the steering angle and the
We are proud to announce that Suspension Secrets is now the title sponsor of the Vision Motorsport Engineering Novice Racing Driver Competition. It is very rare within Motorsport for an opportunity to come along that allows someone with potential, but without the funding, to compete …
The below set up is taken from a NASCAR car. The setup is also for a car travelling around an anti-clockwise oval circuit. The settings would be opposite if the circuit was clockwise. These are a good base setting to set up your rear wheel …
There are two types of touring car; front wheel drive and rear wheel drive. Each type has its own set up due to the nature of how the car transfers its power to the ground. Below are different set ups for front wheel drive touring …
The set ups below are taken from a rear wheel drive professional drag racing car. Different chassis types, tyre widths and wheel bases could warrant slightly different set ups. However, these figures are a good base to set a rear wheel drive drag car up …
The set ups shown below are taken from a Formula 1 car example. They are therefore at the extreme end of the open wheel racing category and can be tuned back slightly towards zero from these figures for slower classes. The below figures are for …
The set ups below are based upon a four wheel drive rally car which has been set up for a high speed loose gravel course. They are a good base setting to set up a four wheel drive rally car to and can be tuned …
