Design, Building, Tuning, and Repair for High Performance Race CarsBy Gareth LindqvistLength10h 56m
About this audiobook
A fast car is a set of decisions you can check. This book gives you the numbers behind each one.
Race Car Chassis and Aerodynamics is a practical engineering manual for anyone who wants to stop guessing and start measuring. It begins at the contact patch, where load sensitivity and slip curves determine how much grip your tyres actually deliver, then works through the chassis as a system: torsional stiffness, roll centres, camber gain, spring and bar choices converted into ride frequencies through the motion ratio, and brake bias and rotor thermal capacity set before you touch the aero.
Four dedicated aerodynamics chapters cover wings in ground effect, diffusers and underbody flow, cooling drag, and how your centre of pressure moves with ride height. Fabrication, welding and crack inspection follow, then a testing chapter on skid-pad runs, damper histograms and setup logging. Every topic is tied to numbers you can check, record and adjust at the track.
What you will learn:
• Read load sensitivity and slip curves to understand what the contact patch is really doing
• Measure chassis torsional stiffness and use it as a setup baseline
• Set roll centres and camber gain deliberately rather than by habit
• Convert spring and anti-roll bar choices into ride frequencies through the motion ratio
• Get brake bias and rotor thermal capacity right before adding downforce
• Design wings in ground effect and manage diffuser and underbody flow
• Reduce cooling drag and predict how centre of pressure moves with ride height
• Fabricate, weld and inspect chassis structures for cracks and repairs
• Run skid-pad tests, read damper histograms and log setups that transfer between sessions
Written for racers, race engineers, fabricators and student formula teams, this book assumes you want the reasoning behind each adjustment, not just a list of settings. If you build, tune or repair high-performance race cars and need the numbers to back your decisions, this is your working reference.
