Saturday (afternoon) & Sunday(morning) March 23 & 24th, 2019 in Amsterdam, Netherlands.

Above diagram is is just one example of what you will learn in the Workshop. It shows how some necessary dimenions and measures are defined, such that RollAxis, RollArm and the position of the CoG's can be calculated. The course shows 170 of these diagrams, all available in a quality coursebook.


'Magic Numbers' helps engineers to get a better technical understanding of their racing car. The content of this course is based on the book 'Praxislehrgang Fahrdynamik' (english: Practical Course Vehicle Dynamics'), which is written in the German language by my co-author Prof Dr Ralph Pütz and myself. However, this course will be english spoken and the handout will be in english too.

This course is based on the fact that nowadays 99,99% of the competitors in motorracing use an existing car, be it new or used. But the question is how well do you know your car? Do you know the rollmoment exact in numbers? Do you know how the rollresistance is being distributed over the front and rearaxis? If you want to stiffen an axis, do you need stiffer springs or a stiffer anti-roll bar? Do you know how to measure the aerodynamic downforce and how this is distributed? What about the Ackermann geometry? etc...

Workshop magic Numbers is made for engineers in professional and top-amateur racing teams as well for automotive students and Mechanical engineering students, who would like to know their car better, and who would like to be able to improve the performance of the racing car by calculations rather than 'gut feeling'.

During the Workshop Magic Numbers the participants will learn how to measure and calculate the most important dimensions (Spring rate, Anti-roll bar spring rate, position of Roll centres, Motion Ratios and the position of the CofG in 3 dimensions).

Based on the results of these calculations very important values like the Rollmoment, Rollresistance and Load Transfer will be calculated. These values are key for the balance of the car during cornering. Besides that,basic measurement methods and calculations will be shown to determine the (aerodynamic) CDA and CLA values without visiting an expensive windtunnel. Also the theory of Ackermann will be explained and a method of determining it on your car will be given. Basic calculations on the shock absorber will be shown, which allows the user to very quickly find the initial shock setting. Finaly it is explained what steps could be taken to understand the transient phase in a corner (between steering-in and mid-cornering) with help from your data acquisition system.

The underlaying theories of all values and measurements will be explained in a clear manner, expended with lots of practical examples as experienced by myself.

The participant of this workshop will return to the team with lots of very usefull calculations and good ideas to prepare the car for next season. Especially the fact that the car will be set up much better initially will save a lot of expensive and time consuming testing at the track!

Please note that only a maximum of 14 participants can be accepted!


- In-house training for your own team
- individual consultancy, performance engineering
- Support of tests at the track, including the preparation of it

SEMINAR 'HANDLING OF RACING CARS' (Not available by now)

This seminar is being followed-up by the Workshop Magic Numbers. No seminars are being planned at short notice, but it is still available upon demand. The key points of this seminar are included in the Workshop Magic Numbers.

Oversteer? Understeer?
Thanks to our seminar you will learn how to analyse this problem, and hence also to solve it quickly!
Why should you spend lots of time and money on your engine any longer, just to gain some tenths of a second, while you can gain full seconds with a well adjusted handling!? This seminar is your quickest route to faster laptimes.

In the seminar Handling of Racingcars you will learn the dynamics and most important adjustments of the suspension system of a racingcar in just two halfdays or evenings. Lots of real-life examples will be based on data generated with a MoTeC Data Acquisition System.

This seminar is meant for:
- Drivers: learn to understand the handling of your car better.
- Engineers/mechanics: better understanding of the theoretical fundament and insight in the consequences of the adjustments.
- Teammanagers: better insight in the decisions made by the driver and engineer/mechanic.
During the seminar you will learn about the most important topics which are related to the handling of a racing car, like tyres, KPI and Caster, Geometry, weighttransfer, principles of the anti-roll bar, springs, Dampers and Aerodynamics.

You will get most of it if you have a technical education or background, or when you are able to understand new concepts. Most important is that the participant is interested in the background of the handling of his racing car.


Get more out of your DATA-ACQUISITION SYSTEM by learning more about the dynamics of your car!
Do you know how your anti-roll bar really is working? Do you know when your shock absorbers are really effective, and when not? Do you really think that you will reduce roll by reducing rideheight? Have you got an idea why eg. your car is neutral in fast corners and under- or oversteered in slow corners? If you know the correct answers on all of these questions there is no need for you to follow this seminar. In all other cases: please subscribe....

Please see the tab ‘What you will learn’ for a detailled overview.
All participants will receive a colour seminar-book with all slides.
The seminar will be given in the English language.
