In Part 2 of The Wind Tunnel Test of the Razor by Roth IMCA Modified we add a 2" flare to the Right Front and Herold Holly goes over some of what we learn by wind tunnel testing a dirt car and how it can be applied to your program. We are still just starting with future video featuring hood placements, front ground clearance, and much more!

The purpose of these videos is to lift the curtain and make this kind of knowledge available to the weekend warriors and regional racers and not just something the national and well funded teams can take part in. We hope this helps everyone on RaceKnowHow understand aero better and does away with some myths over the years. Thank you all our members! More great knowledge to come!
