If you are doing
suspension mods then you first need to know what you have. If you have cheap springs and KYB shocks then change them out. I put the
Eibach Pro
suspension kit on my 96 Cobra and it was the best feeling
suspension I have ever felt on a Stang before. The ride was unbelievable and the handling was better then the Bilstiens the car had with the Eibach sportline springs.
Downside was it was not as low as I would have liked. Now a key factor to a
suspension working right is chasis stifness and bushings. Full length sub frames are a must! They are cheap and make the largest enhancment in the cars "feel". A strut tower brace does make a difference too. You can go all out and get a shock tower brace as well and that will triangulate all the bracing and make for a very ridged chasis
The next step is good
lower control arms. Get some MM or Steeda rear
lower control arms to help with axle hop and to plant better in the corners. Dont worry about replacing the uppers unless their bushings are shot. If the bushings in the uppers are shot then get the FRPP uppers. Too stiff bushings that some other brands have cause
suspension binding and hurt the handeling.
A pan hard bar will also make the car much more stable in corners and much more predictable.
In the front you will want a bumbsteer kit and offset rack bushings also help to keep the car going the direction you pointed it in rough corners.
If your ball joints or front lower control arm bushings are worn then get the FRPP
lower control arms. They are the 03/04 Cobra pieces and are much stronger then the stock ones and have all new bushings and ball joints pressed in already. You can find them all over, hell, I may have a set for sale soon and if so I will post them in the classifieds
Hope this helps
