I have these Sprint springs on my car, I've had them on for about a year now.
Like some others have said, the front sits slightly higher than the rear. At first it kinda bothered me but I got over it quick. If the fronts were any lower it wouldn't be possible to daily drive, I daily drive mine and it scrapes on the deflector all the time on many entrances. The scraping doesn't bother me because it's just the plastic deflector that scrapes and not the actual bumper, anyone who's owned a low car is probably used to scraping on entrances and exits.
I noticed much better handling over the stock sport option springs (I think FE3?) even before my alignment, then I had the car aligned with more aggressive specs and I couldn't of been happier with the springs + the alignment.
Do not change the springs without getting an alignment done, you'll wear out your tires very quick then have a much more expensive bill waiting for you. I've read about people wearing out tires within ~50-100 miles on a misaligned car, so it's not one of those things where you can say it can wait a little while.
I'd say I've been very happy with my Sprint springs, I'm going to be switching to coilovers soon, probably the BC racing ones. But I'd buy those springs again or recommend them to anyone who wants an aggressive drop.
The car sits very low, if you don't want such a dramatic drop you should probably try the Echibach(sp?) springs, which are I think 1.25-1.5 inch vs the 2+ inch drop these Sprint springs will give you.
I purchased mine off of eBay for I think $109 with free shipping, at the time it was less than half the price of any of the competitor springs, though the quality certainly seemed top notch out of the box and have held up fine so far for me.
