Lowering help!
 

okay so i've read forums and forums about lowering a crossfire but still seem to need help. i just need someone to clarify everything i need to buy to lower my 2004 crossfire. i am on stock rims and stock suspension. only thing i have purchased for the project is the springs themselves. i have chose the vogtland 1.2 drop lowering springs. what else is required? thanks in advance.
