Have a quick Link to a longer explanation of the differences between DEFCON levels?

All the DEFCON systems are priced in PAIRS. One set is enough for BOTH the passenger and driver side installations. DEFCON 1 is the firmest drive/feel available on the market and includes PowerFlex front Poly bushings. This system is firmer than the original MK1 OEM arms. DEFCON 2-4 systems replace the front bush with an adapter and a MK1 bush. With DEFCON 2, the rear bush is replaced with the stiffest OEM bush (the MK2 OEM bush). With DEFCON 3, the rear bush is replaced with the stock OEM MK1 bush - this results in a complete MK1-style arm with new bushes. DEFCON 4 does not replace the rear bush - you retain your (potentially worn) stock rear bush. Stock bushes DO split/wear with age/use. You can analyze your own parts to determine if you think you need replacement rear bushes or not, prior to ordering. Note that Control Arm bolts are "stretch" bolts, and intended for single use only. It is highly recommended you re[place them when re-installing the A arms.

question for Steve....
I bought the adapters and the powerflex bushings. What would you recommend I do to the rear bushings for the most performance oriented handling? My car only has 66k on it so I doubt the original bushings are worn out yet.
Thanks in advance.

Parts list and recommendation..>>>
At 66K I'd go ahead and replace the rear bush. You're gonna spend a fair amount of time and money to do this right, for the few bucks more you might as well. Several have noticed cracking of this bushing in cars with lower miles.. These are the MK2 rear bushings..
DEFCON 1 :
Control arm bolt (front) - 2: N 904 840 03
Control arm bolt (rear) - 2: N 102 622 01
Control arm nut (rear) - 2: N 015 081 4
Ball Joint Nuts - 6: N 103 320 01
Front bush: Powerflex
Rear bush: - 2: 8N0 407 181 B

I read all that, was just more looking for driving impressions re: diff stages. >>
So far, I bought all the hardware for Defcon 4. Trying to decide what to do about the rear bushes, as I have less than 30k on my car.

You should already have the stiffer rear front control arm bushings
and since your car is fairly new they aren't worth replacing. Just get the defcon adapters and your choice of bushing, I'd recommend the poly.
