On the page for a coil over kit by West Coast Fiero's, it states that the stock spring rates for a 84-87 Fiero GT are 208 lbs in the front, and 250 in the back. Is this wrong? It would seem like I'm just making the front stiffer and keeping the back the same. Or is that the idea?

The front is probably right. But the back is probably more like 150, not 250.
To put things in perspective, the spring rates for the '88 Fiero are approximately 206 lb/in front and 142 lb/in rear. I doubt the pre-88 are much different. Because the vehicle's weight distribution is basically the same.
I'm sure someone will interject with "yeah, but the '88 suspension is different". Yes, it is. But look at where the springs are mounted. Their mounting locations are virtually the same. So their mechanical advantage against the suspension will be very similar.
