It's been done many different times and there are good results and bad results. When you cut the springs, you also raise the spring rate so it'll have a harsher ride. Now if your trying to make a difference of 1/2" or so, I wuld go ahead and cut the springs but if your trying to go 1-2", I would just buy a tried and true spring that'll get you to your drop goals. It'll probably be less hassle for you in the long run. If you do a search, you'll find many different posts about many different springs, then you can decide which might best suit you. We all have our choice springs.
