I totaly agree Hog I love the drophognutz said:I am going to go with bilstien shocks(from bimmerparts) and struts, H&R sprinks, cc plates and subframe connectors to start with. Unless you plan on autocrossing I think I would do the suspention in stages. that way you don't spend money on things you don't need. If I feel I need more after that I will add it. I have a feeling that will be enough for me.
I know I hate the stock setup but I have no illusions that I am going to be on the track. my car is my daily driver.
rules of thumb so to speek. everyone seems to think koni's are the best they just happen to be the most expensive. I have never heard anything bad about bilstien eccept the price. MOST other shocks and struts you will hear someone have a complaint about now and then. Deciede how much lower you want your car or if you car because some springs have diffenent drops. search the forum for some pics. that is why I chose h&r.
anytime you ask a question like this it help to put down some kind of budget because you can spend $400-$4000 on suspention mods

here is another site to browse.
H&R's give on a stang it looks and performs perfect in my opnion
If I were in the market to do suspension upgrades I would get the
H&R Super Sports(best drop),Bilstien struts and shocks(great quality for the dough),Steeda Caster Chamber Plates(they do a perfect job for alignment and
quality),Maximum Motorsports subframe connectors(good quality and get great results with them) I have to agree that you can't go wrong with
H&R's or Eibach's they are super quality and give great handling!
