Don't get springs. If you are gonna drop your car, do it the right way and get a coil-over kit. You can get the springs alone for 300 from Ground-Control. They are adjustable and will accept any decent shock made. To match them, a good, inexpensive set of shocks are KYB AGX's. $92/shock. So you are looking at 700 overall after shipping and whatnot. Good price for a GREAT feeling ride. As for wheels, get the proper offset, and if you want good tires that last long, take a look at
www.tirerack.com and see what you like, there are a lot of 205/40/17 to choose from.
