HELP? Driver side front lower by 1"????

ok my suspension set up is : Tech 5 lowering springs, KYB AGX struts, SPC ball joint camber kit.
Well i was driving with the windows down today and my stereo turned off for a change, when i heard a swishing sound coming from my driver's side front suspension. I drove home and let the car "rest" for a couple hours. i went to go and check my ride height with a yard stick and my driver's side is lower by about 1 whole inch!!! OMG! WTF?? I couldnt even get my fingers through! Any have any suggestions? Is it a blown strut? or is it cheap springs? PLEASE ANY INSIGHT WOULD BE AWESOME! Thanks Guys!

My first guess would be a broken spring, probably broken 2-3 coil up from the bottom. It's hard to say exactly. the easiest way to tell: remove tire & take a peek.

When i take off my tire, how would i tell if it's a broken spring or not? what does a broken spring look like?

Springs are a coiled round bar piece of metal, you will see a break in the coil & possibly an overlapping of coils. While the car is on the ground push down on that corner listening for clunking - then pin point noise

Check the spring perch too, that's the part where the bottom end of spring sits in the strut. Sometimes those break away

Suspension is nothing to mess around with, if your not sure what to look for then have someone else look at it. You don't want your wheel falling off @ 80mph on the highway.

I.e. Don't drive 80mph on the highway, drive 75!

defective springs/sagging, get replacements from manufacter

i've had blown/dead struts but never sagg more than one inch, because the springs keep the ride height.

so it IS my springs and not my struts? i figure that since the springs were cheap neways they would sag..... right??

Cant say exactly what it is without seeing it. Springs settle but not 1", usually no more than .25"

Go outside and look at it. If it looks unusual them you should know :)
