SS springs & sliders...

how deep are you notching them in and why notch them at all ? your already gaining most of the length of the shackle in drop , you can only notch them in so deep before you create an interference of some sort or another wouldn't it be easier to re-arch your springs or use a lowering block if your trying to get lower ? I totally get why you would notch in the front but it seems like a whole lot of work for almost no pay off doing the back .
