Dear Radical Owner 
 
Many thanks for purchasing a Radical SR4 sportscar. 
 

Whether you intend running your car at trackdays, entering it in sprints and hillclimbs, or 
competing in the wide range of circuit racing available to you, one thing remains constant.  A 
well-maintained and prepared sportscar will ensure that you get the maximum performance 
and reliability that Radical is renowned for the world over. 

 
Radicals have covered hundreds of thousands of trackday, test day and racing miles.  This 
manual highlights many of the lessons and tips we have learned.  Do not start your car until 
you have read it. 

 
Your Radical has been designed with one objective – to give you the ultimate driving 
pleasure! 
 

Happy driving 
 

Mick Hyde
