Supension Help?

[illSHOyou]

I really need some help making my spring selection for my suspension.

The Car;
89 Taurus SHO
24mm Front Sway Bar
28mm Rear Sway Bar
+/- 2900 Curb Weight
18 x 8 Wheel with 245's tires

I don't know what spring I should select. The car will retain the stock suspension design so the choices are Eibachs or Moog CC.

Money is not a issue, but Moog CC are very reasonable. I have the choice of 4 different springs with the Moogs, and I wouldn't be surprised that while not a lowering spring, the Moogs may be stiffer than the more expensive Eibachs, especially the ATX springs designed for heavier car.

My thoughts are that 400 lbs. may be removed from the car, its not going to need as much spring as the ride will naturally become harsher due to sprung weight removed. Another advantage I believe is the fact that the Moogs are not lowering springs, so when I cut coils, I end up with more dead coils gone. The Moogs are already design to resist a loaded up car so with more dead coils gone the cars suspension will tighten up quicker and provide less leaning. Maintaining good suspension geometry is also a priority.

With fairly high spring rates in the back and a 28mm bar the car should resist weight transfer to the back and help keep the front tires planted with the 24mm bar providing good neutral characteristics. Pictures shown in my opinion that SHO's with smaller front bars roll more in the front end during hard corners. I want to retain the 24mm bar and limit roll, but not have a understeering car which is where the 28mm bar comes in.

I just want some thoughts? Opinions? Real world results?

You think into things way too much. It doesn't really matter that much. Any of those springs will suit you just fine, but it sounds like you should go with the Moog since you want somewhat stiffer and cheaper.

"Dead coils" are just that and I don't think they affect the characteristics of the spring very much. Cutting one out isn't going to affect how the spring reacts.

Sway bars shouldn't affect front to rear weight transfer.

I was under the impression that a stiffer/thicker front sway bar meant more understeer, not less. Especially with stiffer springs, you're going to be rolling less anyway, so you don't need such a big sway bar.
