i have to agree 100% with phunk, no matter what springs you use, cut ones compressed ones king springs lovells....if they sit loosely in place when there is no load on the suspention they are all as dodgy as each other
making coliovers or really really soft springs the only better way to get the right height
but as for cut springs, if your an idiot and cut too much off the springs and make your car to low.....you will have a crap ride and cops will notice, strangly the same thing will happen with coilovers set to full low
so first leason, if your an idiot....your an idiot
if you want to do a decent job of cutting the springs, first go to a wreckers and find some springs of the same diameter that are stiffer(200b rears and gemini fronts are a good place to look)....use these to cut down
that way you wont be constantly hitting the bump stops (statement no valid if running stanza or sunny struts

)
when cutting them, make sure not to half cut through any of the coils that you plan on still using by accident
dont just keep cutting to see how cool it looks without springs....just take the springs out first to get that out of your system
stop cutting at a practical but still cool height
once you have your ride height..... smooth off the cut end of the spring, clean the springs up then give them a coat of paint
then if you really feel like spending money on new springs that are just as good as the cut ones painted up.....go ahead
