I recently got my self a new set of front springs the height is 12 inches. The springs that came in the car are almost 15 inches. are the original springs stressed that much or are the new springs to small. if so is it possible to build a spacer or buy a spacer to put in.

What kind of car is it on? On Metric GM's alot of people run either a 12" or 11" front spring.

With 12 inch springs in a metric it is going to sit way to high in the front. The old chevelles ran 12 inch springs but the metrics run 11 inch to stay at factory ride height.

o5Racer is correct 12 inches is way to high of a spring to get correct front end geometry in a metric. If you can run a spacer get 5 1/2 x 9 1/2, if not get the 11 inche springs, Been there done that.

i agree 11" puts steering and arms level works good for me.(helps bumpsteer and helps getmore camber in lf)

If you start off with a 12" spring it gives you room to trim it to hep with set up.

yes but if you trim a spring it gets stiffer so you better get a lighter spring to begin with.

why not get a 9.5 and a spacer , but i would not cut the spring, when you cut it you do alot of things to it, you change the rate, increase it, you also make it into a shorter spring this will make it react stiffer, and faster.
a shorter spring of the same rate as a longer one will react as if it was stiffer and will also react faster.
also most good racing springs area made a certian way like one side is flat so it sets on a cup or adjuster or spacer good and the other side is made to sit down into a spring pocket on the stock lower.
it you cut it make sure to duplicate the bottom so it will sit in the spring pocket right.

What's a suggested height for rear springs I cut a few coils out of the stock ones to lower the CG but have no idea what the rates are. I'm looking at Hypercoil springs (Carrol Smith swore by them).
