Julian Edgar has worked as a teacher, writer, editor and
photographer. His varied career has included editing a national
automotive magazine, and writing for various online and print
magazines for many years.
An enthusiast for all things mechanical and electronic, Julian is a
hands-on car modifier, working from his own well-equipped home
workshop, focusing mainly on suspension, engine management and
aerodynamics. He is also a keen cyclist, and he has designed and
built his own bikes and trikes.
He has written several books about car modifications, aerodynamics
and electronics, as well as more general interest books about
engineering and small-wheeled bicycles, Julian has also made a
series of YouTube videos that discuss the subjects of his
books.
He lives and works in New South Wales, Australia.
A great read for anyone interest in car aerodynamics. tkc (Totalkitcarhttp:/)this is a great practical guide to road car aerodynamics, simply explained, and backed up with plenty of references to industry sources and papers for those who want to find out more. www.silhouet.com. a fascinating book Iain P W Robertson - Freelance
