Z instead of S in Yabutz and Motorsportz?

Obviously, Z is the last letter of the alphabet. Outside of the US the majority of English-speaking people pronounce - Z as Zed (like red). But wait, there's more. The name "zed" is derived from the Greek letter zeta, and a lower case z can be used to represent the damping ratio of a spring-system in engineering and physics - the underlying principle of all racing vehicles and engine design.
