Lowering the stang

For the front you can take the 620's out and cut them to get the ride height that you want, but only do this a little at a time. For example 1/3 of a coil at a time. You can use a cut off wheel to do this, however the more spring you cut the stiffer the spring gets. The stiffer the spring the more harsh the ride.
 
yep... what NCMustang said. Lowering blocks for the rear and cut springs for up front. Have you done the shelby upper control arm drop?? That should give you about 1" more up front. I would cut 1/4" at a time. Also, drive the car around for a while. Coil springs need some time and some miles to settle in. The front may drop another 1/2" without cutting
 
no I was hoping to not have to drop the control arm. I guess I am going to have to but I am doing the work next time. The front springs are one of the only things I am kind of sketchy about doing and it was rather expensive to get them switched this time.
 
You can get stiff clamps that will pull two coils close together to get the front just where you want it. That's what I did. Lots of people don't think this is a good idea, but I did mine over 150,000 miles ago and it is still good to go and I have never had a problem. You don't have to pull the springs to do it either.
 
most of the time on the 620's you don't even need a spring compressor, they will ususally just drop right out with very little help when you get the car jacked all the way up and remove the shocks, but have a spring compressor on hand when you do it just in case, and be really careful when doing it. i would jack the car up but don't remove the shock just yet and wiggle the spring to see if it is really tight or if it moves it around freely, if it moves around pretty easily you should be ok without the compressor, if it is in there pretty tight don't take any chances and use the compressor. but before you do any of this drive it around for at least 2-3 weeks (maybe longer) to let it settle some, the front and rear will generally settle guite a bit usually anywhere from 1/2" to 1", sometimes more sometimes less, but definitely give it some time before you try take it apart again, you could very well end up getting the car too low once it settles
 
yea I only have about 20 miles on the rear and maybe 3 on the front. I plan on waiting a bit just trying to get my options together if I am not happy with it. I will tell you the thing drives great, I am very happy with the feel. Thanks for the help
