Gearboxes and differentials involve ratios, determining car speed for a given engine speed. Suspension setting uses angles and geometry, affecting ease of driving and road holding. Wheel width and diameter are critical to performance – larger diameter discs give better braking. Maths and physics are involved with inlet manifolds and exhaust pipes, relating to wave motion in a tube. It is also important to have a good grip of the science of pressure and electrical resistance.
My favourite subjects were maths and physics because I learned about speed and all sorts of things that relate back to cars. If you want to be a motor mechanic you really should do maths all the way through school to Year 12.
I love being a mechanic, working on cars and seeing the end result. I've raced all sorts of cars from Alfa Romeos to Formula cars. I'm very lucky
