Well getting lowering springs for any car puts more wear on the stock struts then the stock springs do. It will cause them to bottom out thus leading too a blown strut. The best way to lower car is with coilovers. A coilover will replace your stock springs AND struts and are made to take more of a beating then your stock strut will ever take with just a lowering spring. True they are quite a bit more money... 1000 bucks vs only 200 for the springs, but most are fully adjustable, so you can have your car at any height you desire.Been reading around on the eibach pro kit and been seeing one or two people complaining that it's blowing out their shocks...any issues with the koups? i have a 2011 sx myself and plan on ordering the pro kit by the end of june. trying to do a little homework before the fact.
If you want you can buy the springs and run the risk of blowing the shocks and just try driving conservatively, or you can save the extra money for the coils.
