MX5 Miata Racing and Road Performance…..
Suspension Set Up Essentials and Ongoing Advice

Are you an MX5 Miata enthusiast?   Maybe you participate in motorsport - or just enjoy performance driving.  If your MX5 is your passion, then our service is for you. You may have researched and sought advice on what modifications and improvements are open to you.  You may already be developing or racing your car.  Enthusiast owner or seasoned racer, the EBook has exclusive content you will not see anywhere else.  Ongoing email support and bi-monthly updates provides specific help with your car.

First you'll learn everything an MX5 enthusiast needs to know about vehicle dynamics from a driver's perspective.  Then we'll show you the application of the theory, using our Weight Transfer Worksheet (WTW). 

We’ll help you with a framework to develop a way of thinking to help solve handling issues, especially as it pertains to the MX5/Miata.

Basic maths skills are all that is required to take full advantage of the ideas presented (No equations or complex solutions). 

The MX5 Miata formula for pure driving dynamics in a value for money sports car is:-
Light weight, low centre of gravity, front engine rear wheel drive, the weight concentrated within the wheel base and close to 50-50 weight distribution.  For us, rear wheel drive is the best way to go for driving fun and enjoyment. 

With this specification, the MX5 Miata is a brilliant platform for any suspension upgrades, whether it is to replace overly soft OE suspension, **see Note on next page**, or much more, right through to full racing spec.  

Take advantage of our experience modifying and consulting on suspension set up for racing and road performance since 1999.  We can help with your plans for your MX5 Miata.  What areas do you want to improve?

Racers:  We can help answer the question, “What are the areas to work on for greatest improvement in lap time?" You get details of all development work and data on David Stone’s race winning MX5.  We are following all Mazda MX5 racing in America, UK and Europe and engaging with suppliers to keep up with the very latest developments.

We can help with Handling and Suspension Set Up for your car - Racing, Self Constructed, Race/Road Performance, or your Classic/Collectable car .......   

Since 1999, we have advised on all types of cars in circuit racing, rally, tarmac rally, super sprint, drift, performance road cars, classic and sports cars.

Using our Weight Transfer Worksheet (WTW) we can do the necessary calculations to determine a balanced set up, and then find a direction for set up changes to try in testing.  It is a very much a practical exercise - do the baseline set up in the workshop, then test. 

Analyse - Workshop Set Up - Test

When you're flat out building/preparing/racing your car, it is difficult to source all the information you need to understand the suspension set up on your car. 

There are two ways we can work with you.  We can consult with you via email/phone/, assisting you or your technical people to do the work, or we can do a one day assessment of your set up in our workshop at Batemans Bay.  Much of what we do is simplified so you can use the ideas straight away.  Some is unique to us, and some has become common practice in professional racing. 

Based on our experience setting up 100's of race cars, we can get your project moving in the right direction.  This alone will save you time and money.  You will have a better set up and a faster race car.  It is far better to start with a known balanced set up for springs anti-roll bars and shocks, rather than wasting track time/use up the car, testing and racing on unknown spring/anti-roll bar/shock rates.  Professional race engineers will do weight transfer calculations like the WTW, if required, as a quick check.  However, they do have more sophisticated tools - simulation software and testing equipment and data logging. 

To enquire, email me. Describe your car, and class of racing (or road use), and I can get back to you about getting a good suspension set up for your car.

  Based on our knowledge and experience with cars like yours, we can help with your    suspension set up as follows:

  OPTION 1.   We provide you with all the information and help you need to do the Analysis, Workshop Set Up and Track Test procedures yourself.  We send you an input data sheet and Weight Transfer Worksheet (WTW) you can start working on straight away.  We provide email/telephone/skype support.  We can discuss options for all the areas influencing your car's handling.  Irrespective of your experience in racing, I think you will be genuinely surprised at the insights we gain pertaining to your particular car.  Our charge for this service is $500 AUD + GST.  (No GST applicable outside Australia).

  OPTION 2.  Let us do analysis and a one day  suspension set up assessment at our Batemans Bay workshop.  This program could be the key to developing your race car, special project, or performance road car.  

With our procedures, all clients have improved better than 1/2 second to in excess of 2 seconds per lap.  Some have won races for the first time. 

The cost of either option is $550 including GST.

Whatever you race, whatever performance car you build....
You need to know your "Magic Number"!

Every racing car has a magic number.  In fact, everything on four wheels has a magic number.  The magic number represents the set up where the car is balanced mid corner - where the driver reports the handling is to his liking - no excess of oversteer or understeer.

We calculate the magic number in an Excel spreadsheet we have developed and used successfully for all different types of cars - the Weight Transfer Worksheet (WTW).  The WTW is the most accessible, easy to understand set up information/tool available on the internet, or in books, to allow you to quickly develop your car,

This Holden Monaro, for example, is set up on the magic number from the Factory.                         

The WTW represents the simple roll stiffness model of weight transfer, as explained in our presentation "How Does the Driver Control the Car?"  It recognizes the major tuning adjustments we use in suspension set up, eg roll centre height, spring stiffness and anti-roll bar stiffness.  We have concentrated on ease of use and practicality.  Anybody can use it.  Racing and road performance car workshops, or owner/driver preparing your own car, all will find it useful. 

As an example of the way the magic number works, say you have a rear wheel drive sedan with 55% static front weight, such as our Holden Monaro example.  This might infer a magic number of 60.  So we adjust the various inputs in the WTW to reflect this magic number, and change the set up on the car accordingly.  This is your baseline set up.

If it's a road car, you'll find it handles nicely on the road.  For race cars, each time you go racing or testing, when you make changes to the set up, you re-calculate the magic number.  It gives you a direction with your set ups - a higher number is more understeer than the baseline set up, a lower number is less understeer.

You can spec the set up of your car by using our Weight Transfer Worksheet.  Decide never again to fit unknown spring stiffness, anti-roll bar or shock stiffness to your car.  You can be in control.  We provide email support for subscribers. 


Let us do the suspension set up on your car at our Batemans Bay workshop.  This program is the key to developing your race car, special, project, or show car. 

With our procedures, all customers have improved better than 1/2 second to in excess of 2 seconds per laps.  Some have won races for the first time.

Ten Biggest Set Up Mistakes  Thought starters about set up issues.





To enquire, email me. Describe your car and I can get back to you with what we can do to to get a good suspension set up.

Work out the Weight Transfer Worksheet (WTW) numbers for your car.  For the cost of A$500 plus GST (GST free outside Australia), we will ensure that you can determine a baseline suspension set up for your car.  We send you a data sheet, you measure and weigh your car, send your measurements to us via email.  Then we can look at the numbers together to decide what you need eg ride height, roll centre heights, spring and anti-roll bars, shocks, castor, camber, toe.




Road Car Performance 

When we do a performance road car set up, we try to take the driving experience to a new level.  For instance, the popular classic sports and performance cars are still around because people enjoy driving them.  We want to make it a sensational drive.
