That statement is missing key information.
Depending on the springs you use and their rate, combined with stock struts or struts not made to handle such a spring rate, then yes you run the possibility of blowing your struts. However, the right combo might work out great for you, save you some money, and last you quite a few thousand miles.
And as A-sher said, coilovers put you in a whole nother ball game. Much more expensive as well. rougher ride too.
Question number one, is this your DD?
Question two, are you willing to sacrifice ride/comfort for performance/handling or does it not matter to you either way? Or what?
