I quite agree with you mate. Except that you have to consider the full length of the "lever" on the suspension. Which is the outer edge of the wheel.

I was just trying to keep it simple and thought it was worth mentioning because there are people out there that don't realise what effects they might end up causing.

A mate of mine with a small block fitted uprated springs and sway bar to the rear of his car and wondered why he was suddenly oversteering like crazy...
