My mate works for one of the huge well known companies he has to sell a tracking and wheel balancing every day to meet the target figures, aswell as shockers and brake parts it's your choice if you want it most folk don't have a clue and say yes.

And here is the shocker once the gauges are on it's very rare it's ok!

Me only time it gets done is when the tyres are bald on the inside edge but remember power steering also does this to a small degree.
