Suspension Kit Question

I am not super famaliar with suspension but FRPP offers what looks like a nice handling pack, but this pack you mentioned appears it may be even better than the FRPP pack, can someone who knows a little about these items compare the two?

M-2005-FR3
Looking for more street manners and an aggressive lowered stance? Grab hold of our Handling Pack! The uniquely tuned dampers are specifically designed for the lowered stance and cornering of the springs and anti-roll bars that are included in this kit. The Ford Racing strut tower brace stiffens up the front end, putting the power to the ground instead of flexing the chassis. A great way to add a little FR500C to your street Mustang!

Fits 2005-06 Mustang GT Coupe

Kit includes:
Dampers M-18000-A
Lowering Springs M-5300-K
Sway Bars M-5490-A
Strut Tower Brace M-20201-S197

All components are designed to work together as a package

Lowers car approximately 1-1/2"

Dampers, uniquely tuned by Multimatic Motorsports (the same company that makes dampers for the FR500C race car)

I have spent quite a lot of time researching old posts and making calls to suspension vendors in the quest to figuring out what suspension package to buy, so I hope I can help you with the info that I have gleaned…

Eibach Pro Kit Plus- Includes springs, struts, and antisway bars. The sprins and sway bars are quality pieces. However, some say that sway bars should be pretty far down the list on planned suspension mods. They say that (A) beefier sway bars can make for an unnecessarily less comfortable ride and that (B) you should optimize a lot of other suspension pieces before worrying about the gains to be had from bigger antisway bars. One fellow claimed that the dampners included in the Eibach kit are not of good quality, that they are oil filled rather than gas filled. He claimed that oil filled dampners are much more prone to fatigue and failure in high performance driving. I must admit that htis was only one man's opinion, but he seemed to know what he was talking about with suspension mods.

The springs, lower chassis brace, adjustable lower control arms, third link, and panhard bars all seem to be good ideas for increased traction, but not all may not be necessary to achieve the results that you desire. The jacking rails are useless on a non-competition car. Unless I am grossly mistaken on what these are (I am thinking of a tubular steel element allowing you to jack your car at any point along the unibody), they are pointless. They may achieve a subframe-connector like effect, but many doubt the necessity of subframe connectors due to the chassis's stock rigidity. Dead pedal sounds nice, but there are probably cheaper ways of putting one in your car.

FRPP-
The Multimatic dampners are said to be of high quality, but overly stiff, even for the increased rates of lowering springs.

Personally, I would make my own "package" with the following components:

1. H&R, Eibach, or Steeda lowering springs. Choosing a spring just depends on the drop that you want.
2. Adjustable panhard bar and panhard bar brace. These components will help to more positively locate the rear axle in hard cornering.
3. G-Trac (or lower front control arm brace) from Steeda or BMR Fabrication. Ties together front control arms so that geometry is maintained under high loads.
4. Keep the stock struts or upgrade to the adjustable Tokicos when they come off of backorder. Eibach says that their pro kit springs will work with the stock struts. Also, my boss (I work for Latemodel Restoration Supply- a really big 79+ Mustang aftermarket dealer) said that for my purposes I would be more than satisified with stock struts and some new springs.

Thanks alot, that is what i was looking for.

The sway bars are good for adjustability more than for anything else. The S197 pushes under hard cornering (as all stock cars do) and the sway bars provide a easy and effective way to better balance the car. I have Steeda sway bars front and rear and have been very happy with them.

FYI ... just picked up my 07 Stang GT and have been researching suspension kits. I just picked Ford Racing anyway and will install it next week, but learned from my local Ford dealer there's a manufacturer's memo out there stating that the new car warranty may be voided if suspensions are modified using other than FR or Roush. Especially important in that Ford has just announced a drivetrain warranty extension on the 07s out to 5 yrs., 60k! So, just be careful out there!
