lower

If I lower my 04 wrx wagon is there anything I have to do to the drivetrain? I'm new to this whole awd thing lol I just don't wanna blow it up or pop axles or anything or destroy my tranny...thanks

I want to lower my 2009 WRX but not sure which brand would be the best. I have read many good things on RalliTek springs. Let me know what you think? Price and quality.
