spring spacers

I have new stock springs in the rear on my malibu and new small v6 springs up front but the front still sits higher than the back, the car doesn't have alot of driving time on it yet but it doesn't seem like they will ever settle lower than now, can i install spring spacers in the rear to level it out untill the front settle if ever.

any cons to using spacers ?

Ok, then how about these.

Jegs says it spreads the springs apart to raise or flip the brackets to lower the car by compressing the springs.

I got the shortest springs they make for the 6 cylinder engine . i was thinking it would be ALOT shorter instead of higher, good thing i didn't use the v8 springs.

I sure hate fooling with those springs but if they have to come out i will have to do it.

Any idea how long it should take for them to settle, anything i can do to speed it up?

what do i use to cut the springs ,if i have to.
