Many members will say to save your money and get the Koni's. I have heard the Tokico's are known for blowing out and maybe members dislike them along with the KYB. I got an excellent deal on H&R springs. I got them for 175 shipped off ebay, brand new. I am in the same boat as you right now, looking for the right shocks. Many might say to go with the cobra rears and LX fronts. Me, Im thinking of going with the Monroe Sens-trac until I redo everything way down the line. It all depends on how much you want to spend and what kind of ride you want with your bird.
