Question 1)So I want to lower the Cobra 1 to 1.5 inches. I guess my first question is how much will this cost to do it right, without buying the most expensive brands out there?

Question 2) It is unlcear if I can get away with buying lowering springs only or if I have to purchase other items (i.e. c/c plates or struts)?

Question 3) What inexpensive brand do you recommend that will get the job done? Your help is appreciated.
