Modify the aerodynamics of your road or race car for better performance.

• Reduce drag and lift with proven modifications.
• Improve airflow through radiators, intercoolers and oil coolers.
• Measure the effectiveness of undertrays, wings and spoilers.
• Understand the latest advances in car aerodynamics.
• Use practical and low-cost aero testing techniques you’ll find nowhere else.
• Read the views of professional car aerodynamicists from Porsche, Tesla, Rivian, Jaguar and Rover.
• Authoritative, deeply researched and practical.
• 500 pages and 800 colour photos, diagrams and charts.

The one resource you need if you’re modifying or developing vehicle aerodynamics.

“This book puts into the hands of both enthusiasts and professionals an easy to understand, yet technically rigorous, guide to developing and modifying car aerodynamics. Highly recommended.” – Rob Palin, former Tesla lead aerodynamicist

“This shows just what can be achieved without using a wind tunnel or professional level CFD. A very impressive book.” – Dr Jeff Howell, former head of aerodynamics at Rover and Jaguar Land Rover

“Clearly explained concepts, useful and effective test techniques and plenty of example modifications and measurements – this book has everything a home modifier needs to implement successful aerodynamic changes to their own car.” – Jon Young,

Note from the author:

So why is it so expensive? Four reasons. First, Amazon has just lifted their printing costs, due no doubt to worldwide inflation. Second, the book is full colour (i.e. full colour on every page), which adds significantly to printing costs but also makes diagrams, graphs and photographs so much easier to understand. Third, at 500 pages, well over 800 images and 11 x 8.5 x 1.2 inches thick, it’s a large book. Finally, in the context of car modifications – and potentially getting them wrong and so wasting time and money – it’s a cheap investment.

So why no Kindle version? Three reasons. First, any electronic version of a book is immediately pirated. I am not greedy, but I do need some financial recompense for my work. Second, the biggest danger I find with the topic of car aero modification and development is that people look at only a small part of the whole, get the wrong idea and then go off and do bad modifications. With a physical book they are much more likely to leaf through more material, so getting a much better contextual understanding. Finally, I love books. I have a very extensive library and to me, a physical book has so much more to offer than just words and images on a screen.

From the Publisher

Lead the herd – don’t follow it. No more guesswork, rules of thumb or copying others in your car aerodynamic development and modification.

Flow visualisationFlow visualisation

Measure aerodynamic pressures

Directly measure aero pressures on the road or track – optimise spoilers, undertrays and diffusers for best results. Measure and improve flow through intercoolers, oil coolers and radiators.

Measure changes in drag

Measure changes in aerodynamic drag on the road. Optimise bellypans, front air dams and rear spoilers. Test – don’t guess.

Measure lift and downforce

Measure aero lift and downforce on the road or track. Optimise wing and diffuser angles and find best spoiler heights. Cheap, easy and accurate measuring technique.

See airflow

Measure airflow direction and behaviour at zero cost. See how to reduce drag and lift, improve the operation of vents and scoops, and reduce drag from wheels.

Learn how to gain downforce on your high performance track or road car – and it’s easy to do!
