    Hey everybody, a while back I redid the suspension on my 04. I did it somewhat on the cheap because I needed to save money for other modifications. Right now I have KYB agx's front and back on a mild setting with stock springs (feel like that was a bad decision lol) hotchkis rear lower control arms and polly bushings in my front control arms, strut mounts, sway bar mounts and links. The car handles okay but doesn't feel grounded enough in high speed corners. and sometimes coming through rough braking zones even though it's not lowered i get some bump steer. (my guess is the factory springs are collapsing too much under heavy braking)

    My real question is what are you guys running? ultimately I want to go with coilovers and add a rear sway bar. anyone running the QA1 coilovers out there? Should I consider adding a panhard bar also?

    What are your plans with the car, and what are you trying to accomplish? I have the AGX in the front, on setting four with a coilover 350lb spring, and I really like it.

    It's a street car, something i drive hard everyday. What coil over kit do you run? Is your car stock other wise?

    In the front I have the stock lower control arms with Del-A-Lum forward offset busings with Steeda X2 ball joints, steeda bump steer kit, kyb agx strut with a generic coil over kit equipped with the hypercoil 350 lb spring, and maximum motorsports camber/caster plate. I would suggest the mm plates due to the added 4th bolt for both plates. Don't cheap out on this part, as all the weight is now on the plates. In the rear I have the mm rear coil over kit with bilstein shocks with a hypercoil 200-250lb spring( I can't remember), mm panhard bar, and lastly the eibach swaybar kit. The car handles solid, the del a lum bushings take the deflection away, and add caster with improved steering response. The panhard will help with on power turn exit, as well as a more solid feel.

    I suggest not combining a pan hard bar with the oem 4 link. Consider a poor mans 3 link of a torque arm setup is out of budget.

    Agree 100%. The OEM 4 link system will not need a panhard bar at all.

    The first suspension mod I would suggest is welded on sub frame connectors which stiffen the frame twisting significantly. My preference is Steeda's which also comes with torque box stiffeners. There are other companies which sell them. Steeda's are rectangular, first bolt up under the front seat bolts, and can be welded up at any good muffler shop in about 10-15 minutes.

    I did forget to mention that. I do have sub frame connectors, and the brand I use is Maximum Motorsports. I have installed them into two of my mustangs, they fit great, and are top notch in quality.

    As 6shooter sugested this would be a nice addition to the car. If you decide on a weld in style connector, most muffler shops can install them if needed.

    I will say this with the pan hard bar. For street driving you will not notice much difference unless you are driving in areas where you can push the car hard though corners. It made a huge difference on the track. It was a very noticable addition. I do have stock four link, and plan on upgradeing the rear lower control arms to the MM heavy duty units. Keep in mind that I road course this car, and some of the upgrades I listed may not be as benifical or cost effective for daily driving.

    If you wanted to keep things more cost effective you could look at the Steeda sport springs, Eibach pro kit, or H & R Race springs (might need to upgrade the struts & shocks), and add the Eibach sway bar kit. The sway bar will stiffen up your corning. Also, you could set the dampener settings to max (firm). This will help slow down weight transfer. i just re-did the suspension on my 98 GT. I used the Steeda Sport springs, and the Koni Sport (orange) shocks and struts. I would have used the KYB, but I got a great deal on the Koni's.

    1. Tires, 200 tw
    2. Subframe connectors, XL, with seat braces
    3. 35mm front sway bar - or - 30mm bar from sn95 gt
    4. Oem rear sway bar from a gt
    5. R&R all worm bushings and linkages

    After that you should consider long term SRA vs IRS.
