Effects of Lowering Springs
I have a few question that someone might be able to help me with I got this week off work by surprise. I have a set of Eibach Sportline lying around. If I change just the springs and leave my shocks, struts, Panhard bar and LCA brackets alone will it have any ill effects? I will replace theses parts over the next month or so but I have this week off so I am board and want something to do. Will it hurt anything?

They will be fine but lowering springs will eventually destroy your stock shocks/struts. My rears were completely ruined after a year with my springs. Your rear will be miss alligned until you can get an adjustable panhard rod. LCA relocation brackets aren't a must but do put your LCA's back to the stock angle.

Well I did one front in 30min but then I striped my lug nut key
. I have to go tomorrow and have the locks removed. Then I can finish the other 3. A good point to bring up though do not stand in front of the spring when removing it. It flew 3 feet away from the car.

It only flew 3 feet is because it got stuck on the a-arm but the spring was pretty much uncompressed. I can see if I just drop the jack it would go flyin.
You will need to re-align the car after completing the swap. There is a provision in the stock K-Member to loop a chain around the middle coil of the spring and secure it to the K-Member. You can then lower the A-Arm completely and use a hammer to unseat the spring. It will pop out but the chain will prevent it from flying out. This is very dangereous what you did, lucky nobody got hurt. I will have pictures of this entire process soon.
You do not need spring compressors to remove springs on our cars. Installing stock height springs is a different story, in that case I say yes use the compressor.
