Eibach Spring Cracked!!

While replacing the oil pan on my 2004 Mustang I noticed that the driver side spring is cracked! The car is my daily driver and I really don't want to have to buy one spring. I called and left a message with Eibach over the weekend explaining how displeased I was and plan to call them first thing tomorrow morning. What do you think the chances are they will ship me on one the house I need it ASAP? Has anyone else had a problem like this? The part # on the spring is 3510.201 and that is part of the Eibach Pro Kit which was on the car when I bought it 20,000 miles ago.
 
I guess that would depend on how long you have owned the springs. When I installed my FRPP springs one of the stock front springs were broken I never noticed it until then.
 
They will replace it, but you have to send them your old one first. They have to "examine" and go from there. A friend had something similar happen. They told him over the phone it was just a crack in the coating and it was nothing to worry about. He insisted it was a crack, and they had him mail it in. After they examined it, they sent him a new spring with no other information. It took about 2 1/2 weeks for him to get the new spring. I guess it could have been faster if he paid for faster shipping to and from Eibach.
 
So I lucked out. Eibach called me first thing this morning and is sending me an entire Pro Kit not just a replacement spring for the front driver side spring. Only down side is it is shipping via ground from CA and I am from Delaware so it looks like I am looking at 5 business days :/
 
Both my brother & I snapped both our front Eibach springs right at the bend in the lower pearch, we live in Maine with big potholes so Im sure thats what did them in. I remember those spring being so stiff people would joke that I should wear a kidney belt. Ive been running H&R SS springs for the past 4yrs or so and they've been great...they are on the soft side. My next set will be H&R Racing springs.
 
Alright guys so since Eibach was kind enough to ship me a whole replacement pro kit I think it might not be a horrible time to start looking at new struts. Any suggestions for a good combo to go with my lowering springs. The car has roughly 90k on the odometer and I am assuming they are the stock struts although I may be wrong I will have to double check. Its a daily driven car but I like playing in the 'twisties"
 
MM CC plates, tokico blues/eibach shocks/ bilsteins (you can't go wrong with any of them- your stock shocks are almost guaranteed to be completely worn)..... I would also recommend a steeda bumpsteer kit - you don't know how bad the bumpsteer is in our lowered cars until it is gone.

After you install them get your car aligned to the MM specifications. :)
